gen_matypes: fix cross-compiling with gcc
The current gen_matypes logic assumes that the host compiler will produce
information that is useful for the target compiler. Unfortunately, this
is not the case whenever cross-compiling.
When we detect that we're cross-compiling and using GCC, use the target
compiler to produce assembly from the gen_matypes.c source, then process
it with a shell script to create a usable header. This is similar to how
the linux kernel creates its asm-offsets.c file.
