[Bug ada/40288] New: undefined reference to `__gnat_begin_handler' for -mabi=32 on mips64el-linux

[laurent at guerby dot net]

As shown below all gnat.dg tests that need to link are failing for -mabi=32
(they do work for abi=n32 and abi=64).

This is not due to gnatmake or the test harness as it reproduces once the
compiler installed.

Investigating.
