Configuring php3 with DSO support and mySQL adds to Makefile
the following line:

APXS_LDFLAGS =  -Wl,'-rpath /usr/local/lib/mysql'

This is reasonable for compilers (linkers), that support true
dynamic loading, but with systems, like BSDI 3.1, that has
static dynamic loading and dl-style loading this is extra.

This line makes compiling fail during linking. Removing it
solves problem.

Solution: Some sanity check before adding this :>
