Rich Felker 3a0c9775b6 add initial fdpic support 
binutils-2.25.1/0003-shemuls.diff is needed to include the existing
fdpic support in the build when targeting sh*-linux-* rather than
tucking it away under sh*-uclinux-* only

gcc-5.2.0/0007-fdpic.diff is based on the original abandoned fdpic
patch 3/3 sent to the gcc list in 2010, updated for modern gcc and
with the uclinux dependencies removed. the original is here:

  https://gcc.gnu.org/ml/gcc-patches/2010-08/msg01464.html

gcc-5.2.0/0001-musl.diff has been updated to use the right musl
dynamic linker pathname for fdpic so that musl-specific changes can be
avoided in the main fdpic patch.

at present, additional patches to musl are needed to produce working
binaries for the target.

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.
