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).
