current usage within this file is 

#ifdef __PIC__
	this goes into Scrt1.o (for PIE/ET_DYN binaries)
#else
	this goes into crt1.o (for ET_EXEC binaries)
#endif

Scrt1.o is compiled w/ -fPIE/-fpie
crt1.o is compiled independently of DO_PIC always w/o -fPIC/-fpic

there is no support for gcrt1.o (should be added to Makefile.commonarch 
if needed)

PIE is only relevant if you have also CTOR_DTOR (and shared lib support)

__uClibc_main() here

some other files:
Makefile.arch:fpu_control.h is handled generally in topdir/Makefile.in, if 
it exists for this arch it is linked into include/
This file changed somewhat, it includes as last ../Makefile.commonarch,
you have to list only CSRC, SSRC (excluding crt?.S). if you need some 
special header added as link, see mips/Makefile.arch

vfork.c: add libc_hidden_proto(fork) and s/__fork/fork/ (this way it will 
use the internal version of fork)

_mmap.c: rename to mmap.c, else you get duplicate object conflicting w/ 
common/mmap.o[s] (ARCH_OBJS are excluded from common and built here)

Thanks, Peter
