[Pkg-phototools-devel] Bug#980421: libjpeg FTCBFS: fails to compute reasonable compiler identification from cross tools

libjpeg fails to cross build from source, because it attempts to include
a file e.g. Makefile_Settings.arm. The "arm" part here comes from an
attempt at extracting a compiler identification from the compiler
variable. The $ac_tool_prefix confuses the parsing code. It needs to be
stripped of. Please consider applying the attached patch to make libjpeg
cross buildable.
