g2clib fails to cross build from source. A first issue is the use of the
build architecture pkg-config. Making it substitutable via the standard
variable PKG_CONFIG is the solution here. Next, it passes -m64 and
-D__64BIT__ to the compiler. This happens to break the build for almost
any architecture but amd64. Those flags should simply go away. In the
linker stage, the makefile hard codes gcc rather than using CC, which
fails again. Finally make install redoes all the compilation, so we also
need to pass cross tools there. The attached patch fixes all of that.
Please consider applying it.
