build: build deb/rpm independently on config/extensions in the host system Reverts 5aac617a028d and replaces it with a more general solution. - works for both rpm and deb - sidesteps eventual problems with local extensions that have nothing to do with the build process (hg-git, for example, fails with version 4.4 because dedab036215d removed peerrepository, and hg-git still uses it as of 0.8.9)

'''measure performance of Mercurial commands
Using ``hgperf`` instead of ``hg`` measures performance of the target
Mercurial command. For example, the execution below measures
performance of :hg:`heads --topo`::
$ hgperf heads --topo
All command output via ``ui`` is suppressed, and just measurement
result is displayed: see also "perf" extension in "contrib".
Costs of processing before dispatching to the command function like
below are not measured::
- parsing command line (e.g. option validity check)
- reading configuration files in
But ``pre-`` and ``post-`` hook invocation for the target command is
measured, even though these are invoked before or after dispatching to
the command function, because these may be required to repeat
execution of the target command correctly.
