30# Individual makefiles set:
31#
32# USPACE_PREFIX (*) relative path to uspace/ directory
33# SOURCES (*) list of source files
34# LIBS libraries to link with
35# DEFS compiler defines
36# EXTRA_CFLAGS additional flags to pass to C compiler
37# LINKER_SCRIPT linker script
38# PRE_DEPEND targets required for dependency check
39#
40# BINARY (/) binary output name (like appname)
41# LIBRARY (/) library output name (like libname)
42#
43# EXTRA_OUTPUT additional output targets
44# EXTRA_CLEAN additional cleanup targets
45#
46# POSIX_COMPAT set to 'y' to use POSIX compatibility layer
47# NEEDS_MATH set to 'y' to add implementation of mathematical functions
48#
49# Optionally, for a binary:
50# STATIC_NEEDED set to 'y' for init binaries, will build statically
51# linked version
52# STATIC_ONLY set to 'y' if binary cannot be linked dynamically
53# (e.g. uses thread-local variables)
54#
55# Optionally, for a libary:
56# SLIBRARY Name with full version, e.g. libfoo.so.0.0
57# LSONAME Soname / name with short version, e.g. libfoo.so.0
58#
59# (x) required variables
60# (/) exactly one of the variables must be defined
