[llvmlinux] Target beaglebone errors

[Peter Teoh]

I tried compiling for beaglebone as target in verbose mode (make V=1):

Referencing a similar bug report:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=621029

Hmm....I am at a loss what to do?   Appreciate if someone can explain the
meaning of this error:  "/usr/bin/ld.bfd: unrecognised emulation mode:
armelf_linux_eabi"???

Thanks.
