Subject: [PATCH] Avoid flow link error on ppc64 by eliminating bignum_align inlining
The libtoa_stubs.a library created when building ocaml-dtoa on ppc64le
contains the bignum_align.part.4 section created by the compiler
optimizing the bignum_align(). This causes the linking against the
library on ppc64le to report errors like we see when building the
flow package. For example:
/usr/lib/gcc/powerpc64le-alpine-linux-musl/6.4.0/../../../../powerpc64le-alpine-linux-musl/bin/ld: /usr/lib/ocaml/lwt/liblwt_unix_stubs.a(unix_lseek_job.o): In function `result_lseek':
/home/buildozer/aports/testing/ocaml-lwt/src/lwt-3.2.1/_build/default/src/unix/unix_lseek_job.c:113:(.text+0xb8): call to `result_lseek.part.0' lacks nop, can't restore toc; (-mcmodel=small toc adjust stub)
