Yes, I can reproduce this. '--without-lz4' results in:

configure: lz4 configuration via prefix
checking for LZ4_compress_default in -llz4... yes

which is not the intended behaviour. The intended behaviour in that case is to throw an AC_MSG_ERROR:

      AC_MSG_ERROR([Subversion requires LZ4 >= r129, or use --with-lz4=internal])

CCing dev@ for this part.

In principle, if svn were built without lz4 (which isn't supposed to be
allowed by the stock configure) then it won't be able to read or produce
svndiff2 deltas, which are used on the wire and may be used in FSFS f8
on-disk data.
