# glibc-2.3.x passes cross options to $(CC) when generating
# errlist-compat.c, which fails without a real cross-compiler.
# Fortunately, we don't need errlist-compat.c, since we just need .h
# files, so work around this by creating a fake errlist-compat.c and
# satisfying its dependencies. Another workaround might be to tell
# configure to not use any cross options to $(CC). The real fix would
# be to get install-headers to not generate errlist-compat.c.
