2012-06-07avoid linking main program in linker testsRich Felker1-2/+2
it's possible that the user has provided a compiler that does not have any libc to link to, so linking a main program is a bad idea. instead, generate an empty shared library with no dependencies.
2012-06-06make configure try to disable stack protectorRich Felker1-0/+2
in theory we could support stack protector in the libc itself, and users wanting to experiment with such usage could add -fstack-protector to CFLAGS intentionally. but to avoid breakage in the default case, override broken distro-patched gcc that forces stack protector on.
2012-06-06add configure check for gnu linker hash style settingRich Felker1-1/+20
some broken distro-provided toolchains have modified gcc to produce only "gnu hash" dynamic hash table by default. as this is unsupported by musl, that results in a non-working libc.so. we detect and switch this on in configure rather than hard-coding it in the Makefile because it's not supported by old binutils versions, but that might not even be relevant since old binutils versions already fail from -Bsymbolic-functions being missing. at some point I may review whether this should just go in the Makefile...

2012-05-05add -frounding-math to buildRich Felker1-0/+1
2012-05-04initial commit of configure scriptRich Felker1-0/+275
this script is not based on autoconf; however it attempts to follow the same interface contracts for ease of integration with build systems. it is also not necessary to use musl. manually written config.mak files are still supported, as is building without any config.mak at all as long as you are happy with the default options and you supply at least ARCH on the command line to make.
