Hello,
The other day I was attempting a kernel build and stumbled across this:
$ CROSS_COMPILE=foo make
/bin/sh: 1: foogcc: not found
make: foogcc: Command not found
/bin/sh: 1: foogcc: not found
/bin/sh: 1: foogcc: not found

init/Kconfig:16:warning: 'GCC_VERSION': number is invalid
/bin/sh: 1: foogcc: not found
make: foogcc: Command not found
Compiler lacks asm-goto support.
make: *** [arch/x86/Makefile:302: checkbin] Error 1
I had something more sensible for CROSS_COMPILE, but the point is it
did not exist in my $PATH.
I tried the patch below but there's still something calling the
$(CROSS_COMPILE)gcc before gcc-version:
$ CROSS_COMPILE=foo make
/bin/sh: 1: foogcc: not found
make: foogcc: Command not found
Compiler lacks asm-goto support.
This isn't a big deal but if there's a simple fix it would be nice to clean up.
Cheers,
Joel
