The attached fixes the compiler error of asm-source.exp
for m32r-linux target.

In case of m32r-elf target, asm-source test needs to set
stack pointer register. But in m32r-linux target, Linux
kernel sets it and the asm-source test should not change
its value.

OK to commit?

* gdb.asm/asm-source.exp: Add m32r-linux target.
* gdb.asm/m32r-linux.inc: New file.
