Feature request: make it able to compile on ~alpha architecture

[cyborgyn]

Since Alpha architecture is missing newer compilers, like LLVM, clang, rust and others are not available for it, thus most if not all modern browsers are non-compilable on that architecture. PaleMoon can be made to compile on Alpha with some fixes / hacks. So here are my findings:

• env/palemoon.conf: needed to add an additional -DNSS_USE_64 compiler flag:
  • CFLAGS="${COMMON_FLAGS} -DNSS_USE_64"
  • CXXFLAGS="${COMMON_FLAGS} -DNSS_USE_64"
• Needed a patch for config fix
• Needs an other patch (instead of above hack, but failed on that)

For some reason this didn't solve the issue, thus it needed the above CFLAGS hack:

An other patch is also needed for jemalloc, for not to compile static page sizes, as it will not work with alpha:

Hello, I think it would be best to ask for this upstream on forums.
