Subject: using musl-cross-make to build host gcc
Hi,
I would like to compile gcc for my host using musl-cross-make. I copied statically linked tools (cp, mv, sed etc. + musl, zlib) to the new dir (system layout) and, of course musl-cross. Then chroot to dir and built necessary libraries (gmp, mpc, mpfr). I installed new libraries in /usr/local/{include,lib} and also copied them (.so and headers) in to cross/x86_64-linux-musl/{include,lib}. Then I built binutils, which I also installed in /usr/local.
I used all musl-cross-make patches for gcc. The compilation went without any problems. I installed gcc in /usr/local and removed the cross gcc.
After all I could compile binutils and libraries using the new compiler. Unfortunately, the compilation of gcc itself ends with a strange error.

cannot compute sizeof (long long)???

Any idea about what I'm doing wrong?
