   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|softmmu).
