[PATCH] Fix double string quoting.

[Martin Liška]

Hi.

This is a fix for my recent change in string messages.
It fixes:

/bin/sh /home/marxin/Programming/gcc/gcc/../move-if-change tmp-recog.c 
insn-recog.c
/home/marxin/Programming/gcc/gcc/config/aarch64/aarch64.c: In function ‘void 
aarch64_override_options_internal(gcc_options*)’:
/home/marxin/Programming/gcc/gcc/config/aarch64/aarch64.c:11457:14: warning: 
'q' flag used within a quoted sequence [-Wformat=]
       error ("incompatible options %<-mstack-protector-guard=global%> and"
              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
       "%<-mstack-protector-guard-offset=%qs%>",
       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Ready for trunk?
Thanks,
Martin
