[PATCH, i386] Fix PR78478, Compile Error for i386-rtems

[Uros Bizjak]

Hello!

This patch (partially) reverts my change from 2013-11-05. Apparently,
LONG_DOUBLE_TYPE_SIZE interferes with soft-float handling.

    * config/i386/rtemself.h (LONG_DOUBLE_TYPE_SIZE): New define.

Tested by Joel on RTEMS soft-float target.

Committed to mainline SVN.

Uros.
