eglibc_2.13: Resolve multilib header conflicts

Due to mismatches between various header definitions in i386 and x86_64
we need to overwrite the i386 versions of the headers with their x86_64
equivalents.

This can not be done for the syscall.h as it's dynamically generated,
so use the header conflict resolution helper for that.

# We need to ensure that all of the i386 and x86_64 headers are identical
# to support the multilib case. We do this by copying headers from x86_64
# to i386 directories. Normally when hand building eglibc or a combined
# system you would build 32-bit, and then overwrite any files with the x86_64
# versions.
#
# Each time eglibc is updated, this will need to be re-evaluated. In order
# to do this, disable this function. Build eglibc for a 32-bit and a 64-bit
# IA32 target. Compare the contents of the include files -- comments specific
# to the x86_64 version compared to the 32-bit one.
#
# For eglibc 2.13, each conflict noted below:
