You can now run your i386-elf cross toolchain from /opt/src/coreboot/util/crossgcc/xgcc.
        $ make menuconfig # for ASRock E350M1 with SeaBIOS master and 4 MB image
        $ make

I got the following error.

[…]

The file `.xcompile` also contains the correct definition for `IASL`.

IASL:=/opt/src/coreboot/util/crossgcc/xgcc/bin/iasl

Running that file works too so no `noexec` flag or something else seems
to be at fault.

Thanks,
