# cfgtest.sh: sofort's config test framework,
# for use from within a project's custom cfgdefs.sh.
# in the common scenario, target-specific tests are preceded
# by a single invocation of cfgtest_target_section, whereas
# native (build) system tests are preceded by the invocation
# of cfgtest_native_section.
# cfgdefs fraework variables:
# mb_cfgtest_cc: the compiler used for the current test
# mb_cfgtest_cflags: the compiler flags used for the current test
# mb_cfgtest_cfgtype: the type of the current test (target/native)
# mb_cfgtest_makevar: the make variable affected by the current test
# mb_cfgtest_headers: headers for ad-hoc inclusion with the current test
