change = for += is triggering those warnings

./bootstrap 
+ [ ! -e config ]
+ autoreconf -i
tests/benchmark/Makefile.am:2: AM_LDFLAGS must be set with `=' before using `+='
tests/regression/Makefile.am:2: AM_LDFLAGS must be set with `=' before using `+='
tests/unit/Makefile.am:2: AM_LDFLAGS must be set with `=' before using `+='
autoreconf: automake failed with exit status: 1

Will fix in the patch myself.

Thanks,

Mathieu
