# The GNU C Library can't be built for i386.  There are several reasons for
# this restriction.  The primary reason is that i386 lacks the atomic
# operations required to support the current NPTL implementation.  While it is
# possible that such atomic operations could be emulated in the kernel to date
# no such work has been done to enable this.  Even with NPTL disabled you still
# have no atomic.h implementation.  Given the declining use of i386 we disable
# support for building with `-march=i386' or `-mcpu=i386.' We don't explicitly
# check for i386, instead we make sure the compiler has support for inlining
# the builtin __sync_val_compare_and_swap. If it does then we should have no
# problem building for i386.
