Commit: M32R: Fix config problem building m32r-linux toolchains

[Nick Clifton]

Hi Guys,

  I am applying the patch below to fix a small problem building
  m32r-linux toolchains - the glibc-c.o object file was not being built
  because the definition of tmake_file in M32R section of config.gcc was
  not allowing for the inclusion of t-glibc.

Cheers
  Nick

        * config.gcc (m32r-linux): Allow for tmake_file not being empty.
