#9 libnjb location

[Linus Walleij]

On Linux it's a bit problematic when compiling
out-of-the-box, you have to change the hardcoded
location /usr/local/lib/libnjb.so in two places
in src/Makefile.in in order to compile for a
distro.

I have one patch changing it to /usr/lib for
i386 etc and one changing it to /usr/lib64 for
x86_64.

Can this be made configurable? Like
./configure --with-libdir=/usr/local/lib
