subversion: do_install failed (parallel issue)

install-neon-lib needs libsvn_delta-1.la which will be regenerated
during libsvn_delta-1.la's installation, if libsvn_delta-1.la is
in regenerating and at the same time install-neon-lib links it, the
error willl happen.

The error message is:
/bin/ld: cannot find -lsvn_delta-1
collect2: error: ld returned 1 exit status

This is a parallel issue, so it doesn't happen often.

Note:
The autoreconf doesn't generate build-outputs.mk, it would be generated
by autogen.sh (use build.conf as the input), but autogen.sh isn't
suitable for cross compiling, so both modified build-outputs.mk and
build.conf.
