I sent a patch that hugely speeds up lookup_minimal_symbol to
gdb-patches in November.  Give it a try.  My patch works by keeping
two hash tables, one of which is used to deal with the mangling
problem.

The patch has never been checked into the main line of gdb, but it is
"known" to be safe -- no test suite regressions from a gdb using it.
Maybe it will go in someday.
