The cc-rs crate will try to guess the host compiler and use default
flags these are not specifically set. The default behavior is wrong in
Void cross-compilation environments. Explicitly define HOST_CC=gcc and
use innocuous HOST_CFLAGS=-O2 just to thwart the bad defaults.

Closes: #28416.
Packages that link against python3-numpy require special consideration
to ensure that, in a cross-building environment, target libraries and
headers as well as the FORTRAN compiler and linker are properly
identifeid. Previously, this was done directly in the python3-scipy
template to support cross compilation. Now, a build_helper generalizes
these changes to support other package templates.
When cross building a package using build_helper="gir" add the
gtk+3-devel package to the hostmakedepends in case it is
contained in the makedepends.
Remove the specific case in gcr now that this is automatic.
