Rich Felker 0b1f5d1197 replace steps directory with stamp files in source/build dirs 
this makes it easy to rebuild components simply by removing the source
or build directory with rm -rf; no separate action on the steps files
is needed.

some dependencies are also changed to order-only so that
update/rebuild of one component does not force unnecessary rebuild of
another.

new convenience pseudo-targets are also added.

README.md

musl-cross-make

This is a quick and simple makefile-based alternative for producing musl-based cross compilers. In addition to the build system, it provides a number of patches, including:

  • Updated versions of the musl target patches going into upstream GCC

  • Static-PIE support and enabling PIE as default

  • Fixes for SH-specific bugs and bitrot in GCC

  • Support for J2 Core CPU target in GCC & binutils

The current focus is on SH2/J2 Core targets and NOMMU (where PIE is mandatory) since these are not adequately supported by other musl cross-compiler toolchain build systems.

Usage

To build, copy the provided config.mak.dist to config.mak and edit then run make. Parallel builds are supported. The host needs to have suitable gmp/mpfr/mpc libraries installed in the standard library path, or you can add the appropriate --with options to GCC_CONFIG.

At present only GCC 5.2.0 and Binutils 2.25.1 are supported. Backporting of patches is needed to support other versions.

The included patches should also be usable with Gregor's original musl-cross or other build systems, if desired.
