Bug#1069029: libxml-bare-perl FTCBFS: uses the build architecture compiler

[Helmut Grohne]

libxml-bare-perl fails to cross build from source, because it uses the
build architecture compiler. The compiler detection in Makefile.PL
actually is not very smart and just uses "gcc". I am attaching a patch
that makes the CC configurable via environment and falls back to the
detection mechanism of perl itself. While this improves cross building,
I fear the patch will regress msvc builds as is, because earlier getcc
used to return 0 for msvc and now it'll really return a compiler there.
So the patch will work on Debian, but upstream may want to refine it.
