Add local gdb patches.

This shortcuts the canonicalization of symbol names. This is likely to
introduce regressions for setting breakpoints by function names (which
is rarely used by IDE users) but speeds up startup by around 15% for a
typical Qt application. So disabling it seems to be a good compromise.

NOTE: Apply to --target=arm-none-symbianelf builds only.
This works around the problem of TRK overshooting line-wise stepping by a few
instructions. This is not a gdb problem, but a TRK problem, but currently
easier to workaround on the gdb side. It's sufficient to apply for the
arm-none-symbianelf targeted gdbs only as TRK is the only probe known to have
this problem.
