    Require powerpc_vsx_ok in gcc.target/powerpc/pr71763.c
    
    We're getting an error when running this test on PowerPC VxWorks 7,
    due to an unexpected warning:
    
        | Excess errors:
        | cc1: warning: '-mvsx' and '-mno-altivec' are incompatible
    
    The warning comes from a combination of factors:
      - The test itself uses -mvsx explicitly via the following directive:
           // { dg-options "-O1 -mvsx" }
      - Our toolchain was configured so as to make -mno-altivec
        the default;
      - These two options are mutually exclusive.
    
    This commit adds a powerpc_vsx_ok dg-require-effective-target directive
    to that test, and thus making it UNSUPPORTED instead.
    
    Tested on PowerPC VxWorks 7. Also tested on PowerPC ELF as well,
    a platform where we do not make -mno-altivec the default, to verify
    that the test continues to run as usual in that case.

            * gcc.target/powerpc/pr71763.c: Require powerpc_vsx_ok.
    
    (cherry picked from commit c917584aa9ec32934acf0082ed383b04f49fd174)
