   5 # These are complicated by the fact we want to build them for guest
   6 # systems. This requires knowing what guests we are building and which
   7 # ones we have cross-compilers for or docker images with
   8 # cross-compilers.
   9 #
  10 # The tests themselves should be as minimal as possible as
  11 # cross-compilers don't always have a large amount of libraries
  12 # available.
  13 #
  14 # We only include the host build system for SRC_PATH and we don't
  15 # bother with the common rules.mk. We expect the following:
  16 #
  17 #   CC - the C compiler command
  18 #   EXTRA_CFLAGS - any extra CFLAGS
  19 #   BUILD_STATIC - are we building static binaries
  20 #
  21 # By default all tests are statically compiled but some host systems
  22 # may not package static libraries by default. If an external
  23 # cross-compiler can only build dynamic libraries the user might need
  24 # to make extra efforts to ensure ld.so can link at runtime when the
  25 # tests are run.
  26 #
  27 # We also accept SPEED=slow to enable slower running tests
  28 #
  29 # We also expect to be in the tests build dir for the FOO-linux-user.
