This restores part of r359311 that was reverted by r359830. Rewrite the symbol types to fix several issues. Notable difference is that the type of __init_array_start changes from 't' to 'd'. GNU nm used to mark ELF symbols relative to .init_array as 't' https://sourceware.org/bugzilla/show_bug.cgi?id=24505 (before 2.33) because ".init" is the prefix. The bug was copied by r287803.

## We used to be wrong with some linker synthesized symbols.
|
|
|
|
## We mark __init_array_start as 'd', as consistent with GNU nm >= 2.33 (older GNU
|
|
## nm marks it as 't'). See https://sourceware.org/bugzilla/show_bug.cgi?id=24511
