I am able to reproduce the issue with sdk image, The packages(rpms) generated are different in r0 vs r1 version of gmp. Hence you are seeing that issue. Earlier libgmp.so.10 was the only library need packaging, so I guest package name was chosen aslibgmp10. now libgmpxx.so is also part of the package, hence recipe name which is gmp is chosen as the package name.  

$ ls gmp-5.0.2-r0/deploy-rpms/i586/
libgmp10-5.0.2-r0.i586.rpm    libgmp-dev-5.0.2-r0.i586.rpm  libgmp-staticdev-5.0.2-r0.i586.rpm
libgmp-dbg-5.0.2-r0.i586.rpm  libgmp-doc-5.0.2-r0.i586.rpm

$ ls gmp-5.0.2-r1/deploy-rpms/i586/
gmp-5.0.2-r1.i586.rpm      gmp-dev-5.0.2-r1.i586.rpm  gmp-staticdev-5.0.2-r1.i586.rpm
gmp-dbg-5.0.2-r1.i586.rpm  gmp-doc-5.0.2-r1.i586.rpm
