I noticed this incongruity before and decided to leave it as it is,
because it's more of an upstream choice and the only drawback is purely
cosmetic. On the contrary I found changing the library name much more
disruptive on the end user side for those who don't rely on h5*c
scripts: it means having different build scripts depending on the
distro, instead of just setting some '-I' and '-L' options through xxFLAGS.

Hence I'd prefer not to change it.

Thanks,
