    Fix up -Wliteral-suffix warning on mti-linux.h
    
    I've noticed while trying to reproduce PR92989 the following warning:
    In file included from ./tm.h:42,
                     from ../../gcc/backend.h:28,
                     from ../../gcc/lra-assigns.c:80:
    ../../gcc/config/mips/mti-linux.h:31:5: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix]
         "/%{mmicromips:micro}mips%{mel|EL:el}-"MIPS_SYSVERSION_SPEC  \
         ^
    This fixes it, string concatenation works just fine even with whitespace
    in between.

            * config/mips/mti-linux.h (SYSROOT_SUFFIX_SPEC): Add a space in
            between a string literal and MIPS_SYSVERSION_SPEC macro.
