email@example.com is probably the better place for this.

An upgrade is IMHO the best solution:
gcc 3.3 will fix some "branch out of range" issues, and binutils
newer than 126.96.36.199.18 implement multigot. Both together should

These reduce GOT usage at the expense of speed and size, so they
help a bit as workaround.

Would also work, but is binary incompatible then.
