[PATCH 0/1] MR8068: makedep: Build implib code with guest compiler.

[Sasha Finkelstein (＠chaos_princess)]

Some implibs contain code that indirectly includes winnt.h, which in
turn contains NtGetCurrentTeb. On arm64 that is implemented by reading
a global register variable. Gcc is perfectly fine with that, but clang
complains that x18 is not a reserved register on linux.
