+Configure checks for compiler to be gcc and then it enables asm_offsets
+generation. see
+
+https://cgit.freedesktop.org/mesa/mesa/commit/?id=73c9b4b0e05fc66629ba250846948dc55c0e7a0d
+
+However, we missed the check when enabling this on cross compilation
+when architecture for both host and target is x86
+
+Fixes errors like
+./gen_matypes > matypes.h
+/bin/bash: ./gen_matypes: No such file or directory
