Fix testing with read-only source directory.
Three tests fail with a read-only source directory because they try to write into the source directory. None of these write into it in a way that should actually be problematic for concurrent builds sharing the same writable source directory, but avoiding any writing into the source directory (from testing, or from building glibc if the source timestamps are properly ordered) is still a good idea, as being able to build with read-only sources helps make sure there isn't anything that could cause problems for concurrent builds. This patch changes the tests in question to use either /tmp or the build directory to write their temporary files (or to test O_TMPFILE, as applicable). Tested for x86_64. * io/Makefile (tst-open-tmpfile-ARGS): New variable. * posix/tst-mmap-offset.c (fname): Use /tmp. * stdlib/tst-setcontext3.sh (tempfile): Use ${objpfx}.
