369863f015 Allow install SCST in any location 
Currently the install location of SCST is pretty much hard coded into 
the Makefiles to be /usr/local.

I am custom building a system for ZFS & SCST and I want to install in 
/usr instead of /usr/local.

Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.

This patch fixes it.

From Sietse van Zanen <sietse@wizdom.nu>

Now we have sg_next_inline(), so let's use it everywhere.

bd7c893f04 Multiple makefiles: autodetect SCST include directory 
It is cumbersome to change SCST_INC_DIR and SCST_DIR in each Makefile
before and after a release. Hence modify the Makefiles such that these
paths are detected automatically.
