PATCH: correct typo

[Loren James Rittle]

Without this patch, `make check-install' in libstdc++-v3 is broken.

A companion patch (not provided) would force mkcheck to check for an
abnormal return from invocation of tests_flags.

This patch was checked as required on alpha-unknown-freebsd4.2 by
removing the library staging area of a fully bootstrapped tree and
typing gmake at top-level.
