Thierry Reding 2d191bd876 build: allow kmscon to be cross-compiled 
The genshader and genunifont utilities are run during the build process
to generate source files. In order for that to work when cross-compiling
the files need to be built using the native compiler instead of the
cross-compiler.

Add the AX_PROG_CC_FOR_BUILD m4 macro which defines various *_FOR_BUILD
variables that are the native equivalents of CC, CFLAGS, LDFLAGS, etc.
Override CC, CFLAGS and LDFLAGS for genshader and genunifont and their
object files so that they will be built natively and can be executed
during the build.

# pkg-config dependencies
# This unconditionally checks for all dependencies even if they are disabled. We
# later look whether all required depedencies are met and finish the
# configuration. We group similar packages into one logical group here to avoid
# having variables for each single library.
# This, however, makes ./configure output very unintuitive error messages if a
# package is not found so we must make sure we print more verbose messages
# ourself.
