It worked. I removed the declarations of symbols from the patch.

By the way, I noticed another bug in m32r.inc. In m32r.inc, there is
a sequential nop after bl instruction, which is illegal. M32r simulator
doesn't care about it, but real m32r chips cause exceptions.
The attached new patch  fixes this problem too.

* gdb.asm/asm-source.exp : Add -lgloss to link-flags.
* gdb.asm/m32r.inc : Remove an illegal nop after bl instruction.
Replace ld24 with seth/add3.
