Actually the bug goes deeper than this.  The test for creating the
library with an soname is done on a per-language basis by looking for
one of the above variables, but the test for installing the library with
an soname is done using the ..._SONAME_C_FLAG variable.  The install
test should be changed to use the target's linker language just like the
build test.
