Patch to fix the pgsql linker path.

The problem occurs because they find the postgresql linker path with pg_config. 

$ pg_config --libdir

But then miss the required -L so that they pass the file directly to the compiler which obviously does not work.

rdlibtool: link: gcc .libs/dbd_pgsql.o -std=gnu99 /usr/lib64/postgresql-13/lib64 -lpq -L/usr/lib64 -ldbi -shared -fPIC -Wl,--no-undefined -o .libs/
/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: read in flex scanner failed

Simply adding the missing -L solves this and I guess this is another thing GNU libtool silently filters out...
