That’s not the whole makefile, can you verify that it’s actually using ${CC}
and not gcc in every build step?
Run file on the libiobb.a to verify it contains what you expect.
Also install the library to ${D}${libdir}, /usr/local/ is for non-managed files
and by writing a recipe it’s managed.
I also note that iobb is long-dead so there might be a better alternative now.
