Drop GLIBC_TUNABLES for setxid programs when tunables is disabled (bz #21073)
A setxid program that uses a glibc with tunables disabled may pass on GLIBC_TUNABLES as is to its child processes. If the child process ends up using a different glibc that has tunables enabled, it will end up getting access to unsafe tunables. To fix this, remove GLIBC_TUNABLES from the environment for setxid process. * sysdeps/generic/unsecvars.h: Add GLIBC_TUNABLES. * elf/tst-env-setuid-tunables.c (test_child_tunables)[!HAVE_TUNABLES]: Verify that GLIBC_TUNABLES is removed in a setgid process.
