Set `BUILD_CC' to the compiler to use for programs run on the build system as part of compiling the library. You may need to set `AR' to cross-compiling versions of `ar' if the native tools are not configured to work with object files for -the target you configured for. +the target you configured for. When cross-compiling the GNU C Library, +it may be tested using `make check +test-wrapper="SRCDIR/scripts/cross-test-ssh.sh HOSTNAME"', where SRCDIR +is the absolute directory name for the main source directory and +HOSTNAME is the host name of a system that can run the newly built +binaries of the GNU C Library.
