Proposed patch

I've recently detected an inconsistency between ld.bfd and ld.gold on ARM platforms. It seems that Gold does not set entry flag in ELF header:

# Binutils with --enable-gold=no
$ arm-v7a15v5r0-linux-gnueabi-gcc justmain.c
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
  ...
  Flags:                             0x5000202, has entry point, Version5 EABI, <unknown>

# Binutils with --enable-gold=default
$ arm-v7a15v5r0-linux-gnueabi-gcc justmain.c
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
  ...
  Flags:                             0x5000000, Version5 EABI

The attached simple patch seems to fix this:
$ arm-v7a15v5r0-linux-gnueabi-readelf -h a.out
ELF Header:
  ...
  Flags:                             0x5000002, has entry point, Version5 EABI
