patch: use mkinstalldirs when installing multilibs

[Aldy Hernandez]

When doing a "make install" on the e500, the installation dies when
it tries to create a directory without the parent directories (this is
while mkdir-ing one of the gazillion multilib directories).

Is this ok for mainline and e500 branch?

Tested by doing a make install on powerpc-eabispe.

	* mklibgcc.in: Use mkinstalldirs when installing multilib
	directories.
