Don't mix LDFLAGS and LIBS in the configure script

Browse Source 
* configure.in: If you pass libraries in the LDFLAGS variable, and then
  try AC_CHECK_FUNCS to find whether a function is present or not,
  it'll fail badly when using the --as-needed linker flag. Instead,
  pass the libraries through the LIBS library, so that they are passed
  after the conftest.c source file and the tests are done properly.
