It would be more future-proof to use 'substitute-keyword-arguments' here,
as possibly a future package definition of 'gdb' could set #:configure-flags.

It would also be nice to adjust the description and synopsis a bit.
Maybe something like

 (synopsis "The GNU debugger for remotely debugging msp430 systems")
 (description "This is the GNU debugger, configured for debugging msp430 systems
from a system of another architecture.")

and add to the description of 'gdb' something like

 "This variant of the GNU debugger only supports debugging programs compiled for
the same architecture as the GNU debugger runs on.  For remote debugging, the
variants @code{gdb-msp430} or @code{gdb-arm-none-eabi} may be required."

(Assuming that's correct.)  (These descriptions could be improved.)

Greetings,
Maxime.
