Re: Compilation speed of Linaro's gcc compared to e.g. Ubuntu's version

I think I've found the problem. We pass -U_FORTIFY and -fno-stack-protector to make the binary more universal, and the way that crosstool-NG passes these flags on to the tool overrides the default package flags and turns off any optimisations.

Short story: GCC was being built without optimisations. I've got a test build running to verify.

setting STAGE1_CFLAGS should not overwrite the CFLAGS used for the build. Setting these flags for a native stage3 build should not be necessary. The stage1 compiler isn't shipped.
