Why don't you just install /usr/local/lib/gcc44/ with a
different version number?  There is no requirement to sequentially
assign numbers thus: use 10MmX where X is the number assigned by GNU
and Mm is the major/minor number as used by the port.  Then, install
in standard port place and let standard rules find the right library.
(e.g. lang/gcc44 would use: /usr/local/lib/;
lang/gcc45 would use: /usr/local/lib/

I can't vouch for having tested it recently (or ever) but:

Add --enable-rpath to the configure line.
