Usually this means the macro was only invoked conditionally. Makefile:19843: recipe for target 'configure-target-libgfortran' failed make[1]: *** [configure-target-libgfortran] Error 1 make[1]: *** Waiting for unfinished jobs.... Even if you disable this error, bootstrap fails due to trying to build x86 specific files: gcc/libgfortran/generated/matmulavx128_i1.c -fPIC -DPIC -o .libs/matmulavx128_i1.o xgcc: error: unrecognized command line option ‘-mprefer-avx128’ make[3]: *** [matmulavx128_i1.lo] Error 1
