Subject: Building Matlab Channel Access with Base R3.15.7

Recent attempts to build the Matlab channel access extension on my OS X machine resulted in

The mca extension build system doesn’t use any of the EPICS build stuff and thus must be told the location of the compiler-specific headers.
Also, the dbStaticHost library doesn’t seem to exist now, but removing the reference to it doesn’t seem to hurt things.

Here’s my quick fix — should work on Linux too, but not tested:
