This combination is broken since 7.0.4-6.

Since commit a9e228f8ac26 (Implemented a private PNG caNv (canvas) chunk),
PNGsLong gets called unconditionally, but it is only defined if JPEG
support is enabled (which defines JNG_SUPPORTED), breaking the build:

MagickCore/.libs/libMagickCore-7.Q16HDRI.a(MagickCore_libMagickCore_7_Q16HDRI_la-png.o): In function `WriteOnePNGImage':
png.c:(.text+0x748d): undefined reference to `PNGsLong'
png.c:(.text+0x74b7): undefined reference to `PNGsLong'

Fix it by adding a patch unconditionally defining the helper function.

Patch submitted upstream.
