[PATCH] Add -nodefaultlibs while compiling against klibc

[PATCH] Add -nodefaultlibs while compiling against klibc

[Martin Hicks]

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.

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.

s390 seems fail as well, have to verify it.
