Bug#819466: alien: DEB->RPM does not setup Provides for shared libraries properly

[Matthew Gabeler-Lee <cheetah@fastcat.org>]

Package: alien
Version: 8.95
Severity: normal

Example: Converting the debian liblockfile1 and lockfile-progs to RPM
packages, because CentOS packages totally broken and useless versions of
these.

The converted lockfile-progs has these Requires:

libc.so.6
libc.so.6(GLIBC_2.0)
liblockfile.so.1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PartialHardlinkSets) <= 4.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1

But the converted liblockfile1 only has these Provides:

liblockfile1 = 1.09-7
liblockfile1(x86-32) = 1.09-7

Note that the provides and requires for the shared library are totally
disjoint, resulting in the application RPM not being installable!
