Hi,
a build of GHC with SplitObjs=NO on OpenBSD fails when trying to
link utils/installPackage during stage2, because it references some
symbols contained in libpthread. This problem has been seen earlier,
but it wasn't clear that it's related to SplitObjs. Partial build
output:
gmake -C utils with-stage-2
gmake[1]: Entering directory `/var/tmp/ghc/ghc-head/utils'
gmake -C installPackage with-stage-2
gmake[2]: Entering directory `/var/tmp/ghc/ghc-head/utils/installPackage'

Semaphore.o is pulled in via Posix.o which is pulled in via
libHSdirectory(Directory.o). I wonder wether this works on any
unix-like system when SplitObjs=NO.
My only idea how to fix this it to add -pthread to cc-options and
ld-options of unix.buildinfo if SplitObjs=NO, but this sounds like
a crude hack to me.
If anyone has a better solution, please let me know.
Ciao,
Kili
