New subject: [LinuxBIOS] [PATCH] Add the CPU_OPT flag to facilitate passing flags into the build

30 Oct 2007

buildROM subverts the CPU_OPT flag to pass in flags to the LinuxBIOS build,
especially -fno-stack-protector.  This adds $(CPU_OPT) to one of the targets
in the new GA-2761GXDK build to avoid getting the hated _stack_chk_failed
error.

[LINUXBIOS] Add the CPU_OPT flag to facilitate passing flags into the build

buildROM passes build flags through the CPU_OPT environment variable - 
especially -fno-stack-protector for those of us lucky enough to have
Debian/Ubuntu.  This adds $(CPU_OPT) to the cache_as_ram_auto.inc target
for the GA-2761GXDK so that the resulting cpu0.S is clean.
