configure: Add -DGRUB_HAS_PCI when compiling C/C++ files on targets that support PCI

Browse Source 
The list of targets that support PCI is in gentpl.py. However, there is no
support for generating makefile script from a .def file that will apply
globally to the makefile, but on a per target basis. So instead, use
gentpl.py in configure to get the list of targets and check if the current
build target is one of them. If it is, set the automake conditional
COND_HAVE_PCI. Then in conf/Makefile.common add -DGRUB_HAS_PCI for the
platform if COND_HAVE_PCI is true.
