I am not sure, if I did something wrong. But I applied this patch, compiling still fails for me on arm.

I cannot reproduce this on an arm system, so this should be reassigend to arm64 only. An emerge --info to see which gcc and libc you use would be helpfull too.
Comment 4 Lars Wendler (Polynomial-C) (RETIRED) gentoo-dev 2017-07-28 07:09:03 UTC 
According to the changelog of libpng-1.6.31 this has been fixed:

  Revised pngpriv.h to work around failure to compile arm/filter_neon.S
    ("typedef" directive is unrecognized by the assembler). The problem
    was introduced in libpng-1.6.30beta01.

Can somebody confirm this?
