Re: Include assembly entry points in TAGS

As it stands, etags doesn't find labels in the IA64 or i386 assembler source
code, because they're disguised inside a preprocessor macro.

I propose the attached fix, which adds a regular expression to enable
labels disguised by ENTRY() and GLOBAL_ENTRY() macros.

There's a similar problem for MIPS, which needs to match LEAF(entrypoint)

If you're using Emacs and TAGS, it's useful to be able to get the
global assembler variables as tags into the TAGS file. But they're
hidden by a macro. This patch teaches etags about the macro.
