[patch, mips] Fix -mno-shared option (gcc.target/mips/pr35802.c)

[Steve Ellcey]

The test gcc.target/mips/pr35802.c is failing with the message:

        xgcc: error: unrecognized command line option '-mdsp-mno-shared'

Obviously the -mdsp and -mno-shared flags got stuck together without
a space between them.  This patch fixes the failure.  Ok to checkin?
It was tested with no regressions.

        * config/mips/gnu-user.h (NO_SHARED_SPECS): Add space before option.
