Log Message:
Fix breakage added in last commits in mysql4-* packages:

* Make mysql4-client build on NetBSD 1.[56]*
* Don't install mysqld and friends in mysql4-client (eww!)
* Remove an unneeded patch.
* Remove duplicated files in mysql4-client's PLIST.

Also, use assembler functions when MACHINE_ARCH == i386.

This closes PR pkg/27154, pkg/27720, pkg/27744 and pkg/28035.

BTW, I tested them on NetBSD 1.6.2, 2.0_RC4 and -current.

Bump PKGREVISION for both packages.
