Ticket 49141 - Enable tcmalloc
Bug Description: tcmallon conflicts with asan. Additionally,
tcmalloc needs to use -lpthread, so we should guarantee this with
the use of the pkg-config file.
Fix Description: Fix the rpm to use asan *or* tcmalloc. Fix
configure to explode if you try and use both. Fix m4/tcmalloc to
use pkg-config file. Update bundled tcmalloc link to apply to all
binaries to ensure proper behaviour of the server. This also limits
tcmalloc to supported arches (IE exclude s390)
