Add -nodefaultlibs while compiling against klibc
PATCH 1/1 Add -nodefaultlibs while compiling against klibc
Greg,
This patch adds -nodefaultlibs to LDFLAGS when compiling udev against klibc. This fixes the warning that I was getting when using $(LD)=gcc in the versions after Makefile.klibc disappeared. The problem was that it was still including a "-lc" in the call to the linker.

Thanks, I've applied this.

this gives me linker errors on ppc and ia64:

Nope. I had to do something very similar to what Olaf posted for ppc to get ia64 to compile again. Judging from the Makefile.inc in other arches this is the correct thing to do.
I wonder what I compiled when I tested that patch? Obviously not a build against klibc...
Attached is the patch that I'm going to send to the klibc list for ia64. I'll let Olaf send the ppc fixes. I don't have a ppc machine. mh

s390 seems fail as well, have to verify it.
