[patch] Support gcore for i386 inferiors on amd64

[Jan Kratochvil <jan dot kratochvil at redhat dot com>]

Hi,

currently "gcore" command creates invalid core file for i386 (32-bit) inferiors
running on amd64 gdb/machine.

bfd interface lacks the proper support so it is supplying its own
implementation of 32-bit target while running on 64-bit built bfd.

Patch mostly created by Fujitsu.

Attached glibc patch for review for a possible push there.
Still the gdb patch fallbacks on its copy in the case of legacy/current glibc.


Regards,
Jan
