Subject: shared musl with PCC as system compiler

This is mainly a mix of what I've worked out previously and what Rich and I worked out on IRC. I figured posting it on the list would help those who want to use pcc as compiler...
0. Get today's (Oct 13) git HEAD or later! Otherwise will be broken.
Get a fairly recent pcc from CVS (the last month should be good enough)
When compiling pcc-libs, use 
(otherwise you get textrels in, which doesn't work)
1. Set LIBCC to -L$(dirname `pcc -print-file-name=libpcc.a`) -lpcc 
#-lpccsoftfloat may be needed for some systems
2. Add 
to config.mak (pcc doesn't define this with -fPIC at present, which is a bug)
3. Find the right -m* options:
ld -march=native 
#look for the elf_* in the "Supported emulations" that matches your CPU
Change all occurences of -m* in config.mak to "-melf_<arch>"
(pcc doesn't parse -m*, which is at best an incompatible behavior)
4. Now you should be set to compile.
