building port graphics/ImageMagick
I see these warnings repeated quite often:

{standard input}: Assembler messages:
{standard input}:4334: Warning: Additional NOP may be necessary to workaround It
anium processor A/B step errata

in this context:

I wonder if these are indicative of some serious issue?
