[PATCH/obvious?] Fix typo in gdb/frv-linux-tdep.c

[Sergio Durigan Junior]

Hi,

My xscreensaver is programmed to display GDB code when the computer is
idle.  I found this some day when I looked at the screen before
unlocking it.

I have the strong feeling that this is a typo, but I am in no way expert
in this architecture to know, nor I have means to test this
modification.

WDYT?
