Bugzilla Bug 83112

emerge gnuserv fails here.  This example is using FEATURES="-distcc -ccache"
and MAKEOPTS="-j1",  for simplicity:

(configure stuff... looks okay)
gcc -c -I. -I. -DHAVE_CONFIG_H -I/usr/X11R6/include -O2 -march=athlon-xp
-fomit-frame-pointer -pipe gnuserv.c
gcc -c -I. -I. -DHAVE_CONFIG_H -I/usr/X11R6/include -O2 -march=athlon-xp

make: *** [gnuserv] Error 1

!!! ERROR: app-emacs/gnuserv-3.12.5 failed.
!!! Function src_compile, Line 26, Exitcode 2
!!! (no error message)
!!! If you need support, post the topmost build error, NOT this status message.

Note: I have sucessfully compiled with LDFLAGS disabled.  This was the same
LDFLAGS problem that occurs with emacs.  E.G., bug 77430

Okay, thanks for the bug report. I unset LDFLAGS in the ebuilds.
