crt: Need a position-independent CRT for PIE
- Implement the greatest possible part of the crt1 in C
- Implement SPARC versions of the ASM sections of crt1
- Build crt1 position-independently, minor ASM updates to be position
independent
- Implement crt1 with the hook expected by modern GCC to support
profiling, make gcrt1 a symlink for source compatibility (older GCC
initializes profiling at firsnt use of _mcount if necessary, so
doesn't need the gcrt)
- Split the CRT out of developer/library/lint into a separate c-runtime package
