Bug#888635: firefox: FTBFS on ppc64el: jit unexpected alignment requirements

[Aaron M. Ucko]

Source: firefox
Version: 58.0-1
Severity: serious
Tags: patch upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-powerpc at lists.debian.org
Usertags: ppc64el
Control: forwarded -1 https://bugzilla.mozilla.org/show_bug.cgi?id=1425413

Builds of firefox for ppc64el have been failing lately.  As of 58.0-1,
the (immediate) problem is

  /<<PKGBUILDDIR>>/js/src/jit/Linker.cpp:27:5: error: static assertion failed: Unexpected alignment requirements
       static_assert(CodeAlignment >= ExecutableAllocatorAlignment,

This appears to be the same problem as in
https://bugzilla.mozilla.org/show_bug.cgi?id=1425413, reportedly fixed
upstream with a one-line patch:

https://hg.mozilla.org/integration/mozilla-inbound/rev/34839f53008f

Could you please take a look?

Thanks!
