cb6029f089 configure: Add detection of the linker version string.
- Review appreciated, as long as you understand that I understand that this is
   a horrible hack.

b533fafb38 Fix an autoconf bug: The second argument to AC_LANG_PROGRAM is code that
gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail, 
leaving their options disabled.

This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.

This also includes a regenerated configure, as the diff is small and telling.

377a5d7751 Add an autoconf check for -retain-symbols-file and conditionalize
use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

50c248824a Remove unneeded checks from configure.ac.
HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
bison and flex are no longer used.
CAN_DLOPEN_SELF was never used either.
AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
libltdl checks for dlopen.
Add check for AR, it used to be done by AC_PROG_LIBTOOL.
AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
void.
Remove unused m4 files.
Configure can now be generated using autoconf 2.65 too, without any warnings!

a2401a5692 On Linux, uname -m reports the kernel type. Some Linux systems are 32-bit but
with a 64-bit kernel, which confuses LLVM. Make LLVM double-check this by

fa5014e918 Update to llvm-config tool, by Erik Kidd:
1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.

This version is now ready for testing by users.

7942e8a63f Add a parameter to the FIND_STD_PROGRAM macro that allows an alternate name
for the command line options. This helps with situations where the executable
name sought is too generic and a more meaningful name needs to be used for
the command line options. It also helps satisfy picky project leaders.

bd640a379e Add two new checks for use in LLVM configuration files:
* FIND_STD_PROGRAM will find a program in the path or using --with options
  and verify that the path/bin/program is executable. Also allows checking
  for include files and libraries. If found, USE_PROGRAM is set, otherwise
  its not set. Also sets PROGRAM_BIN (bin directory), and PROGRAM_DIR (top
  level directory). If headers are found, sets PROGRAM_INC. If libraries
  are found, sets PROGRAM_LIB.
* CHECK_PROGRAM_SANITY can be used to run a program with some option that
  only produces information output and requires no input. If the output
  matches a regular expression, the program passes the sanity check.
  Otherwise, an error occurs.

b48ff21894 This macro cannot assume that the location of install-sh and mkinstalldirs
is in ${srcdir}/autoconf because that is only true if the project is LLVM.
For other projects (e.g. sample), we don't want to have to distribute the
mkinstalldirs or install-sh programs because it opens a window of breakage
for projects. So, this change requires that the llvm_src variable be set
up via another AC_CONFIG_COMMANDS call. For LLVM this is done in the
configure.ac. For projects its done in the LLVM_CONFIG_PROJECT macro.

It was moved here from the project's configure.ac file because there is
some tricky handling of the llvm_src variable to tell the project where the
llvm source tree is (for mkinstalldirs and install-sh commands).
