I can confirm that the GNU linker is *not* compatible with GHS binaries;
GHS objects use differently-numbered relocations, for one.

I gave up trying to get the two to interoperate when I found that ld
interprets relocations according to the first (??) input file's BFD,
instead of, say, translating all relocs to target-agnostic BFD ones
first, then linking, then rendering the leftover relocs according to the
*output* file BFD.

(I really needed just to link my poor-man's pthreads into an existing
project, but *wanted* to build it all with a GNU toolchain.)
