[krbdev.mit.edu #8487] 'krb5-config --libs' does not show '-lkrb5support' [Version: krb5-1.14.3]

[Greg Hudson via RT]

The --enable-static --disable-shared configure flags for krb5 aren't 
supported, and should probably be removed.  They was added so that we could 
use gcov to measure the code coverage of our test suite, but gcov now 
supports shared libraries.

We definitely don't want to output -lkrb5support for everyone in krb5-
config; that would unnecessarily include libkrb5support in the direct 
library dependencies of programs built against krb5.
