I've tested on a powerpc machine running debian sid, starting at the
current HEAD (1c7d767b4ca224e26b7d7d3875d2d89201accb29); at the HEAD,
"make check" passes all tests with no problems.

With simon's 0001-Add-salsa20_core-function.patch applied (i manually
tuned the Changelog entry), i get:

PASS: gosthash94
PASS: ripemd160
Assert failed 193: MEMEQ (SALSA20_BLOCK_SIZE, dst,
H("a41f859c6608cc993b81cacb020cef05" "044b2181a2fd337dfd7b1c6396682f29"
"b4393168e3c9e6bcfe6bc5b7a06d96ba" "e424cc102c91745c24ad673dc7618f81"))
Aborted
FAIL: salsa20
PASS: sha1

I'd be happy to figure out how to give access to this powerpc machine if
any of y'all want it, or to make other changes and test them on this
big-endian machine.
