Mariadb101 does compile on i386 if use gcc

[Dewayne Geraghty]

While working through my ports' patches to revert the local changes for
libressl [Thanks to John Marino, your ssl commits are appreciated :) ], I
came across this for
/usr/ports/databases/mariadb101-server/Makefile

-NOT_FOR_ARCHS=         i386
-NOT_FOR_ARCHS_REASON=  currently does not compile on i386, see \
-                       https://mariadb.atlassian.net/browse/MDEV-9627
+#NOT_FOR_ARCHS=                i386
+#NOT_FOR_ARCHS_REASON= currently does not compile on i386, see \

+USE_GCC=               any

This might help others using mariadb on i386.
