Commit years-old change for gcc on NetDSB/mips.

Browse Source 
The NetbSD libc header files use GCC attributes to emit link-time warning
messages (e.g,. for gets()).   SO, add a definition of the GCC back-end
macro ASM_OUTPUT_SECTION_NAME() to the mips back-end target-specific file.

This adds support for emitting warning attributes to binutils 2.6 or newer.
(Weak references may or may not work also).

This patch has been  submitted to the FSF but hasn't made it into 2.7.2.1,
and seems to have got buried somewhere inside Cygnus.
