Explicitly link SRT0.o (Standalone RunTime startup code) first.
This is my fault on changes to make mvme68k bootloaders use MI libsa:
http://mail-index.netbsd.org/source-changes/2011/01/02/msg016539.html
MVME PROM requires raw binaries (by objcopy -O binary) so we have to
make sure the entry point is located at the first address of the binaries.
The problem (6.1 netboot fails with an illegal instruction message)
is reported by Andrew Gillham on port-mvme68k@:
http://mail-index.netbsd.org/port-mvme68k/2013/09/17/msg000082.html
Note mvme68k bootloadres in netbsd-6 still have another bug triggered
by gcc-4.5.
Should be pulled up to netbsd-6 branches.
Make MVMEPROM_ARG2() macro take two args in a single asm statement.
Fixes a problem that a wrong address is passed to the MVMEPROM outstr
function (then caused garbages on screen) after we switched to gcc-4.5.

No error on "build.sh -m mvme68k build" builds.
Should be pulled up to netbsd-6 branches.

Explicitly link srt0.o (Standalone RunTime startup code) first.
Taken from the similar fix of mvme68k:
http://mail-index.netbsd.org/source-changes/2013/09/21/msg047819.html
MVME PROM requires raw binaries (by objcopy -O binary) so we have to
make sure the entry point is located at the first address of the binaries.
The original changes to switch to using MI libsa is:
http://mail-index.netbsd.org/source-changes/2011/01/02/msg016563.html
Should be pulled up to netbsd-6 branches.
(though untested since there seems no users of mvmeppc)
