Patchwork [3/4] gmp: also generate the libgmpcxx library & package it properly

From: Nitin A Kamble <nitin.a.kamble@intel.com>

configure runs few checks to make sure c++ compiler and runtime are working
as expected with the --enable-cxx=detect option. And it enables building
of libgmpxx library.

Same as earlier the libgmp.so.10.x file is packaged in the libgmp10 package,
and a new package named libgmpxx4 is added for libgmpxx.so.4.x file.

Why didn't you let the system to name the package using the soname by
itself and avoid putting the soname on the glob matching?

Before the generation of libgmpxx library, there was only one library, libgmp, and it was getting packaged into libgmp10 package. After addition of the libgmpxx library the package name changed to the recipe name (gmp), in order to preserve the previous package name(for distro upgrades), and to let people avoid installation of libgmpxx if they don't need it in order to save the space on target, two packages are generated for each library with this scheme.

Right, but that's not really the point.  I think what Otavio was trying
to ask was, why didn't you just do:

PACKAGES =+ "libgmpxx"
FILES_libgmpxx = "${libdir}/libgmpxx${SOLIBS}"

?  I think the way you have done it will cause the libgmp package name
to change for people not using debian.bbclass, which is probably a bad
thing.

Thanks Phil,
  This was also works the same. And producing same rpm packages as previous one. So I am happy to accept this change if it helps the deb packages. Will resend the commit.
