libspashscreen / libpng Error

When building jdk7/build/linux-amd64/lib/amd64/libsplashscreen.so, a series of link errors occur, such as this one:

jdk7/build/linux-amd64/tmp/sun/sun.awt/splashscreen/obj64/png.o(.text+0xc3c): In function `png_init_mmx_flags':
: undefined reference to `png_mmx_support'

It has been reported that this problem is fixed internally, but hasn't been integrated into the public mercurial repo yet: http://mail.openjdk.java.net/pipermail/discuss/2007-December/000945.html

In the meantime, there is workaround. Here is a simple patch:
