Here is an example of linker plugin without using GCC:

https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/testplug.c;h=cec947c51c44e7e4334036ecfe96392eb7c32643;hb=HEAD

I'd like to put such plugin under a non-GPL license.

As I understand, Cary, as the contributor of include/plugin-api.h,
may release it under a different license.  Of course, changing license
of include/plugin-api.h in GCC source tree may need FSF approval.
Should we ask FSF to get an approval?
