binaries of the GNU C Library. The source and build directories must
be visible at the same locations on both the build system and HOSTNAME.
In general, when testing the GNU C Library, `test-wrapper' may be set
to the name and arguments of any program to run newly built binaries.
This program must preserve the arguments to the binary being run, its
working directory, all environment variables set as part of testing and
the standard input, output and error file descriptors. If
`TEST-WRAPPER env' will not work to run a program with environment
variables set, then `test-wrapper-env' must be set to a program that
runs a newly built program with environment variable assignments in
effect, those assignments being specified as `VAR=VALUE' before the
name of the program to be run.
