[Jehan <jehanp src gnome org>]

commit fcb161c3f8f6d560ae9ed05d71fff82b4d75e4d7

    Change order of CFLAGS for SSE tests
    
    This makes the configure tests for SSE support fail if CFLAGS specify -mno-sse2 or/and -mno-sse4.1.
    Fixes #4363.
    
    (cherry picked from commit 0108d7e21446024f9ddbcba996cf53a2f39f46e6)
