multimedia/libvpx and netbsd 5

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

Just came across:

    [CC] vp8/common/x86/variance_ssse3.c.o
libtool: compile:  cc -O2 -m32 -O3 -fPIC -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -Wdeclaration-after-statement 
-Wdisabled-optimization -Wpointer-arith -Wcast-qual 
-Wimplicit-function-declaration -Wuninitialized -Wunused-variable 
-Wno-unused-function -I. 
-I/usr/obj/pkgsrc/multimedia/libvpx/work.i386/libvpx-1.3.0 -mssse3 -c 
vp8/common/x86/variance_ssse3.c  -fPIC -DPIC -o 
vp8/common/x86/.libs/variance_ssse3.c.o
cc1: error: unrecognized command line option "-mssse3"

while building multimedia/libvpx, which makes NetBSD 5's gcc 4.1.3 unhappy:

$ gcc -o hellow hellow.c -mssse3
cc1: error: unrecognized command line option "-mssse3"

NetBSD 6's gcc 4.5.3 is happy...

Cheers,

Patrick
