GNU readelf tool prints slightly different dynamic table "header" and surrounds dynamic tag names by brackets. This patch implements the same formatting for GNU-style output of the `llvm-readobj`. LLVM ``` DynamicSection [ (13 entries) Tag Type Name/Value 0x00000006 SYMTAB 0x168 ... ] ``` GNU ``` Dynamic section at offset 0x1d0 contains 13 entries: Tag Type Name/Value 0x00000006 (SYMTAB) 0x168 ... ``` Differential Revision: https://reviews.llvm.org/D62256 llvm-svn: 361633
