I'm pretty sure this patch is Linux-specific. My fear is that it
might be specific to particular versions of binutils and/or particular
Linux distributions... I smell a portability nightmare!
Note that in 3.11, the "configure" script will have options to specify
how to call the assembler (for ocamlopt-generated assembly code and
for the hand-written asm files in the runtime system). So it might be
sufficient to configure the Gentoo packages with e.g.
configure -as "as --noexecstack" -aspp "gcc -c -Wa,--noexecstack"
This could be one of the rare cases where addressing the issue at the
level of the packages is safer than by changing the source distribution.
