Hi,

I tried to compile simh natively on my Beaglebone Black (hf).

The compilation failed with:

* Package: app-emulation/simh-3.9.0-r1
* Repository: gentoo
* Maintainer: alex.buell@munted.eu xmw@gentoo.org,proxy-maint@gentoo.org
* USE: arm elibc_glibc kernel_linux userland_GNU
* FEATURES: preserve-libs sandbox

the standard build runs the compiler with the -flto option (I think
it's Link Time Optimization), which apparently is not supported on the
ARM/Angstrom GCC build. The simplest thing to do would be to cut and
paste the gcc command without the -flto option and run it on the
command line; it's a standard trick for working around Makefile/build
issues. When you find the combination that works, of course fix your
makefiles and submit the patch to the upstream.
