[PATCH] alpha: math-emu: Fix modular build

From: Ben Hutchings (ben@xxxxxxxxxxxxxxx)
Date: Tue Jul 18 2017 - 20:02:06 EST

Commit 00fc0e0dda62 ("alpha: move exports to actual definitions") also
removed the exports of the math emulator hooks, which are defined in C
code. In case anyone cares about the option of CONFIG_MATHEMU=m, add
exports next to those definitions. Also add a MODULE_LICENSE.

Fixes: 00fc0e0dda62 ("alpha: move exports to actual definitions")
Signed-off-by: Ben Hutchings <ben@xxxxxxxxxxxxxxx>
This is build-tested only.
