Subject: [PATCH] libretro-fsuae: add host build for gen target as designed

The host utils are meant to be build on the host (using the host
libaries.) This fixes the error when the glibc libraries are older on
the build host, than the target.

  ./gen/build68k < ./src/table68k > ./gen/cpudefs.c
  ./gen/build68k: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./gen/build68k)
  make[1]: *** [Makefile:2011: gen/cpudefs.c] Error 1
