No, on Linux "make check" always works. We use libtool and that means
that the executable subversion/clients/cmdline/svn is a script that
will relink against the build libraries to produce an executable and
run that. So "make check" uses the build libraries whether or not you
have installed libraries.

I use a shared build on Linux all the time. I use a configure prefix
of /usr/local/subversion and my build produces

$ file subversion/clients/cmdline/svn
subversion/clients/cmdline/svn: Bourne shell script text executable
$ ldd subversion/clients/cmdline/.libs/lt-svn | grep delta
        libsvn_delta-1.so.0 => /home/pm/sw/subversion/obj/subversion/libsvn_delta/.libs/libsvn_delta-1.so.0 (0x40086000)
$ ldd subversion/libsvn_delta/.libs/libsvn_delta-1.so | grep subr
        libsvn_subr-1.so.0 => /home/pm/sw/subversion/obj/subversion/libsvn_subr/.libs/libsvn_subr-1.so.0 (0x40011000)
