[oe] [meta-oe][PATCH] openldap: fix native LDFLAGS build error

[Ioan-Adrian Ratiu]

LDFLAGS += "-pthread" adds the flag both for native and target builds,
however the openldap-native build overwrites the variable inside
native.bbclass causing "undefined reference to `pthread_getspecific'"
and other linker errors.

Change the append to happen after parsing by using the override
syntax and thus make sure it executes after native.bbclass (bitbake -e
reports pre-expansion value "${BUILD_LDFLAGS} -pthread").
