[TS-2334] --with-tcmalloc does not test whether the "found" library actually exists

Description

Our TS_CHECK_TCMALLOC does not work.

I found this when compiling --with-tcmalloc on Ubuntu, where the tcmalloc library is called tcmalloc_minimal. (And its corresponding -dev package, will, intuitively be named libgoogle-perftools-dev. )

But none of this actually matters. I don't need to have any tcmalloc libraries installed for this to fail horribly: ltcmalloc will be added to the build simply because I specified -with-tcmalloc this causes pretty much everything in the configure run to break, or at least run with defaults. (e.g.: glibc2 is not recognized to have a reentrant gethostbyname(), see TS-2331)

proposal: ACTUALLY check if tcmalloc can be found, abort configure if it can't.
