The varargs code for SVR4 puts all (integer) arguments in 4-byte slots.
When it then reads an item from there as something not a multiple of 4
bytes, it needs to adjust the address if big endian. We didn't yet do
that.
This fixes the g++.dg/abi/scoped1.C, gcc.dg/compat/scalar-by-value-4,
and gcc.dg/compat/scalar-return-4 testcases.

Some fixes that permit misc/cgo/test in the master gc repository to
pass using the current gccgo.
Install testing/internal/testdeps.gox; it is needed by `go test`.
Export runtime.lockedOSThread to enable calling via go:linkname; it is
used by misc/cgo/test.
Loop on EAGAIN when creating a new thread; this is what the gc code
does, and misc/cgo/test tests that it works.
