System emulation tests do not run in a hosted environment, since they do not link with libc. They should only use freestanding headers (float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h, stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding in order to use the compiler implementation of those headers rather than the one in libc. Some tests are using inttypes.h instead of stdint.h, so fix that. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

# 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.
