# Individual makefiles set:

#       USPACE_PREFIX   relative path to uspace/ directory
#       LIBS            libraries to link with (with relative path)
#       EXTRA_CFLAGS    additional flags to pass to C compiler
#       JOB             job file name (like appname.job)
#       OUTPUT          output binary name (like appname)
#       SOURCES         list of source files
