[PATCH] static klibc udev does not link against crt0.o

[PATCH] static klibc udev does not link against crt0.o

[Olaf Hering]

no crt0.o means no _start which means no environ which means segfault in
start in getenv.c

Or is there a reason to not link agaisnt crt0.o? Would be bad for ppc32.

Use Makefile.klibc to build with klibc.  If you look at the bk tree this
is all fixed up.  I'll try to make a release in a few days.

I dont understand that.

please do rm -f Makefile.klibc; apply this patch and tell me what fails.
works for me.

Doh, thanks, I've applied this and deleted Makefile.klibc.  Thanks a lot
for this.
