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.
