Test the lowest and the highest real-time signals. This requires configuring the real-time signal mapping, and therefore some knowledge about the host. To this end, pass the emulator path in the QEMU environment variable to all tests (this should not disturb the existing ones), and assume that all hosts have signals 36-39 available.

# These are complicated by the fact we want to build them for guest

|
# systems. This requires knowing what guests we are building and which
|
|
# ones we have cross-compilers for or docker images with
|
|
# cross-compilers.
|
|
#
|
|
# The tests themselves should be as minimal as possible as
|
|
# cross-compilers don't always have a large amount of libraries
|
|
# available.
|
|
#
|
|
# We only include the host build system for SRC_PATH and we don't
|
|
# bother with the common rules.mk. We expect the following:
|
|
#
|
|
# CC - the C compiler command
|
|
# EXTRA_CFLAGS - any extra CFLAGS
|
|
# BUILD_STATIC - are we building static binaries
|
|
#
|
|
# By default all tests are statically compiled but some host systems
|
|
# may not package static libraries by default. If an external
|
|
# cross-compiler can only build dynamic libraries the user might need
|
|
# to make extra efforts to ensure ld.so can link at runtime when the
|
|
# tests are run.
|
|
#
|
|
# We also accept SPEED=slow to enable slower running tests
|
