[Factor-talk] Building a dynamic binary on Linux which fetches .so's from cwd

"on Linux, there is no way to build an executable which looks for a
required shared library in the same directory as the executable
itself."

Not a problem here:

% cat > libtest.c << EOF
void test() { }
EOF
% cat > tester.c << EOF
extern void test();

int
main() {
  test();
}
EOF
% gcc -o libtest.so -shared libtest.c
% gcc tester.c libtest.so
% grep a.out <(nm ./a.out)    # (my pipe key is broken)
         U test
% ldd ./a.out
        linux-gate.so.1 =>  (0xffffe000)
        libtest.so (0xb7fce000)
        libc.so.6 => /lib/libc.so.6 (0xb7e9f000)
        /lib/ld-linux.so.2 (0xb7fd1000)
% ./a.out
% rm libtest.so
% ./a.out
./a.out: error while loading shared libraries: libtest.so: cannot open
shared object file: No such file or directory
