Re: [Tinycc-devel] Cross-compiling tcc from macOS to Linux

[Michael Ackermann]

Two patches are attached to help with cross-compiling with tinycc and
cross-compiling tinycc itself:

tcc-9999-library_path.patch to override system include and library search path
tcc-9999-makefile_cross.patch to address cross-compilation issues

Furthermore it helped to disable bounds-checker and backtrace options.

Since i maintain a complete distribution compiled with just tinycc containing
~500 builds with patches and hacks applied each i cannot refine all those
in detail to comply with various quality assurance acceptance criteria.

If anyone got an idea how to improve upon those two patches then suggestions are
welcome.
