>Description:

A build of gcc in pkgsrc/lang/gcc fails. Seen during the build:

checking whether the C compiler (/local/pkgobj/lang/gcc/work/objdir/gcc/xgcc -B/local/pkgobj/lang/gcc/work/objdir/gcc/ -B/usr/pkg/gcc-2.95.3/alpha--netbsd/bin/ -O2 -mieee -I/usr/pkg/include ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
gmake[1]: Entering directory `/local/pkgobj/lang/gcc/work/objdir/alpha--netbsd/libio'

>How-To-Repeat:

Well, I can't build Perl out of pkgsrc on my Alpha (a 164LX running
1.6). It looks like I need the pkgsrc gcc. So, I go to compile gcc
out of pkgsrc (the build of Perl didn't do it automatically). 

cd /usr/pkgsrc/lang/gcc ; make package

Time passes, bison gets installed, gcc goes back to building, then
blammo!

Scroll back through my xterm and I eventually spot the problem. I don't
know the solution. 

>Fix:

Figure out why gcc wants ld to use elf64alpha instead of elf64alpha_nbsd?
