Found the problem in config.log:

    configure:19617: gcc -o conftest  -I/usr/include/gdal  conftest.c 
-lgdal  -L/usr/lib -lgdal1.7.0 >&5
    /usr/bin/ld: cannot find -lgdal

The configure script is trying to link against both libgdal and 
libgdal1.7.0, but libgdal.so does not exist, only libgdal1.7.0.so. 
According to config.log, this has been identified and stored in 

    LIBGDAL_LDFLAGS='-L/usr/lib -lgdal1.7.0'

But the test scripts are still trying to pass `-lgdal`. Looks like a bug in 
the PostGIS configure script.
