configure: don't clobber environment LDFLAGS

configure.ac was explicitly setting LDFLAGS causing the users
environment supplied LDFLAGS to have no effect.  This resulted in
some strange linking issues, especially when the developer relies
on the environment LDFLAGS to specify custom library paths.

Append the environment LDFLAGS to the configure.ac LDFLAGS.
