Subject: libzzip 0.13.60

 - Fix link error with clang

Fix a link error with clang & libtool. Configure chooses
  --export-dynamic
but that flag doesn't normally start with two dashes, only one.
There are no overrides or switches available for that.  The fix is an
inline patch for configure, adding the compiler case for darwin*) to set
ZZIPLIB_LDFLAGS="-export-dynamic".  Add the inline patch and bug report
url to the formula.  Add the 2sec make check for this compression
library.  Checks on Lion 10.7.3 and SL 10.6.8 with all five compilers
from the 4.3 CLT and XCode-4.0.2 (4D502).

Closes #10672.
