Put the align directive after .text...

773ab1dd74
Put back __RCSID(): The problem was that if RCSID ended up in the text segment,
...
it was placed before `start', and start ended up misaligned. Add an alignment
directive for the start symbol. Of course ld(1) should not core-dump relocating
misaligned symbols, but this will be fixed shortly.

Expects additional register-passed arguments from the kernel on

adjusting the current $sp with a hard-coded frame offset for __start's
local frame(!).

stackframe offsets updated by Jonathan Stone.

and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

add a hack so that old- and new-toolchain alphas do the right thing:

include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN,

routines. Eventually, there should be better ways to distinguish what
toolchain and object format is in use, and the Alpha C++ startup code
changes should be merged with that used by the other ports.
