Add a test to check for duplicate definitions in the static library
This change follows two previous fixes addressing multiple definitions of __memcpy_chk and __mempcpy_chk functions on i586, and __memmove_chk and __memset_chk functions on i686. The test is intended to prevent such issues from occurring in the future. Signed-off-by: Gabi Falk <gabifalk@gmx.com> Reviewed-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Dmitry V.
