This fixes a problem reported for the RISC-V Haiku OS port, where putting
STARTFILE_PREFIX_SPEC in riscv.h breaks their port because they put
libraries in different directories than the UNIX convention.  The current
definition is definitely needed for Linux.  It should not be needed for rtems
or embedded elf which use cross compilers.  It may or may not be needed for
FreeBSD, I can't easily tell, but it is harmless, and can be removed later if
they don't want it.  So I'm moving the definition from riscv.h into the
freebsd.h and linux.h files.

Tested with cross builds and make checks for riscv32-elf and riscv64-linux.
There were no regressions.  Also tested by checking the --print-search-dirs
output for elf, linux, and freebsd cross compiler builds.


Committed.

Jim
