variable telling if static library is enabled

[Peter Johansson]

Hello,

We use libtool to create a library and in the test suite we are trying 
to link against this library statically. The problem is that this test 
will obviously fail when no static library was created, i.e., only 
shared library was created. IIUC, this might happen on some platforms 
but also if the user issues `./configure --disable-static'.

I wonder if there is any variable available that I can use to decide 
whether I should skip the test. For example, if there is some shell 
variable available in the configure script I could easily propagate it 
to the test script. Just searching for static in configure, I found a 
variable $enable_static, and it seems to work the few test cases I've 
tried, but if anyone knows of a better way I would like to know.

Thank you.

Peter
