One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.
