$(prefix) is expanded to a path. It is no longer a variable.
Here's how my variables look on Ubuntu 18.04:
PREFIX: /usr/local
LIBDIR: /usr/local/lib
AUTOCONF_BUILD: x86_64-pc-linux-gnu
PKG_CONFIG_PATH: /usr/local/lib/pkgconfig
CPPFLAGS: -I/usr/local/include -DNDEBUG
ASFLAGS: -Wa,--noexecstack
CFLAGS: -g2 -O2 -march=native -fPIC -pthread
CXXFLAGS: -g2 -O2 -march=native -fPIC -pthread
LDFLAGS: -L/usr/local/lib -Wl,-R,'$ORIGIN/../lib'
-Wl,-R,/usr/local/lib -Wl,--enable-new-dtags -Wl,-z,relro -Wl,-z,now
-Wl,-z,noexecstack -Wl,-z,origin
LDLIBS: -ldl -lpthread
It looks like Nettle is one of three libraries that don't handle the
rpath tokens well. The other two are Perl and OpenLDAP.
Nettle is pretty easy to fix with editelf and patchelf. I can patch
the programs and libraries after 'make' and 'make check'. Perl and
OpenLDAP resist the fix by building shit during 'make install'. I
don't have access to the programs and libraries at that point.
