# Defining this means build targets will first try to use source from this
# directory before falling back to unoptimized i386 source.
#
# Currently, the only differences between hwcap1 and hwcap2 are the kernel entry
# method (hwcap1 uses "sysenter" and hwcap2 uses "syscall"), and sse2 vs sse
# in the optimized assembler routines. Neither difference merits splitting the
# source. So for now, build libc_hwcap2 with the optimized sources for
# libc_hwcap1.
