[hackers] [st][PATCH] Add total compability to the Makefiles

From: Roberto E. Vargas Caballero <k0ga_AT_shike2.com>
Date: Thu, 16 Jul 2015 08:33:03 +0200

With .POSIX target we get that the user
without environment will execute c99. If the user
has no c99, then he can source env.sh or execute
build.sh.
