If I were you, I'd go to test out the solution suggested by Christoph
Junghans.

adding "src_compile() { default AM_CCASFLAGS=; }" to
libpng-1.5.14.ebuild

How?

    $ cd $EPREFIX/usr/portage/media-libs/libpng/

edit libpng-1.5.14.ebuild and add the line.

after that 

    $ ebuild libpng-1.5.14.ebuild digest

which will recalculate the manifests.

Then "emerge libpng" will work in the modified way.

However, if you sync your tree, this modification well be washed out.

That's where an overlay steps in: a place of your own modifications that
is "overlayed" on top of the official portage tree.

Hope this explanation helps.

Yours,
Benda
