recipes-devtools: fix segfault in lib32-gcc with "." multilib_dir

When enabling a lib32-gcc in a 64 bit build, without doing any
other configuration, the mutilib dir is unspecified, which is
represented internally in gcc as "." and as such uncovers an
invalid free on a non-malloc'd pointer.

As suggested by the gcc folks, simply make sure the "." case
is also stored in a malloc'd pointer, so that the intended
runtime behaviour of the code remains unchanged.

Patch has been accepted by upstream maintainers of gcc.
