Geoff Levand bf705ad0c3 frv: Remove redundant debugging info flag
The generic makefile now sets '-Wa,--gdwarf2' in KBUILD_AFLAGS, so
this setting is no longer needed in arch makefiles.

Also remove a commented out addition of a -O1 to KBUILD_CFLAGS, and
comment text relating to these removed lines.
