It can, but it's not trivial.

If the CPU isn't an x86, you need to rebuild the whole toolchain (gcc,
as, ld) from original sources as a cross-compiler.

If the CPU *is* an x86, you still will probably have to use a custom
linker script and write a small converter to convert the COFF output
to whatever your target uses.

You'll likely have to write support libraries as well, but that's a
given with embedded programming.
