[PATCH 1/2] mini-os: fix testbuilds regarding CONFIG_XC

[Juergen Gross <jgross@xxxxxxxx>]

CONFIG_GC is requiring external support, so disable it in testbuilds.

The only reason this is working right now is its usage being inside
a HAVE_LIBC section.

Make that more obvious by making the default setting of CONFIG_XC
depending on libc being available.
