I'm using the GCC 3.2 toolchain for building U-Boot (current head of git) for an ARM target. I get the following error: cc1: invalid option 'abi=apcs-gnu'
This option (correct me if I'm wrong) was introduced with a recent patch by Peter Pearse. Digging a bit in gcc.gnu.org it appears that this option comes only with GCC 4.0!
That's true but the cc-option checker should use -mapcs-32 if it is available, otherwise it will fall back to -mabi=apcs-gnu. It looks like your compiler doesn't support the first option either. In this case, I'm not sure it worked before Peter's patch. What CPU is it?
You could try the following in your config.mk but you should investigate why -mapcs-32 doesn't work:
PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,$(call cc-option,-mabi=apcs-gnu,))
