scst: Avoid that smatch complains about dead code
The panic() function that implements BUG() has been declared with attribute
noreturn in some RHEL 5 kernel headers and also in the RHEL 6 kernel headers.
Smatch warns about dead code if any code follows a function that has been
declared with attribute noreturn. Hence add a few preprocessor statements to
suppress the smatch warning when building against an upstream kernel or when
building against RHEL 6 or later.

This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files.
