### i686-specific code in the boot loader is a bad idea; disabling to ensure
### at least some compatibility if the hard drive is moved to an older or
### incompatible system.
# grub-0.95 added -fno-stack-protector detection, to disable ssp for stage2,
# but the objcopy's (faulty) test fails if -fstack-protector is default.
# create a cache telling configure that objcopy is ok, and add -C to econf
# to make use of the cache.
#
# CFLAGS has to be undefined running econf, else -fno-stack-protector detection fails.
# STAGE2_CFLAGS is not allowed to be used on emake command-line, it overwrites
# -fno-stack-protector detected by configure, removed from netboot's emake.
