What this function does?
I saw in openSUSE SRPM that option --with-wide-int is used.
In Fedora or RHEL we are not using it.

Options which are used for compiling are:

Building emacs package on Fedora or even on OpenSuse works fine.
But under RHEL-7 still fails.
Emacs is build up with full RELRO, though.

emacs is SPEC file is compiled so that
in %prep section is:
- setup
- patching some files
- ./autogen.sh

%build section for emacs-gtk:
- ./configure is called.
- make bootstrap
- make

%build section for emacs-nox is:
- ./configure is called.
- make

Is this correct?

Part of code which is relevant is from src/unexelf.c:
=A0 for (n =3D new_file_h->e_phnum; --n >=3D 0; )
=A0=A0=A0 {
=A0=A0=A0=A0=A0 /* Compute maximum of all requirements for alignment of s=
ection.=A0 */
=A0=A0=A0=A0=A0 ElfW (Word) alignment =3D (NEW_PROGRAM_H (n)).p_align;
=A0=A0=A0=A0=A0 if ((OLD_SECTION_H (old_bss_index)).sh_addralign > ali=
gnment)
=A0=A0=A0 alignment =3D OLD_SECTION_H (old_bss_index).sh_addralign;

#ifdef __sgi
=A0=A0=A0 =A0 /* According to r02kar@x4u2.desy.de (Karsten Kuenne)

=A0=A0=A0 =A0=A0=A0=A0 always get "Program segment above .bss" when dumpi=

=A0=A0=A0=A0=A0 if (old_sbss_index !=3D -1)
#endif /* __sgi */
=A0=A0=A0=A0=A0 if (NEW_PROGRAM_H (n).p_vaddr + NEW_PROGRAM_H (n).p_files=
z
=A0=A0=A0 =A0 > (old_sbss_index =3D=3D -1
=A0=A0=A0 =A0=A0=A0=A0 ? old_bss_addr
=A0=A0=A0 =A0=A0=A0=A0 : round_up (old_bss_addr, alignment)))
=A0=A0=A0 =A0 fatal ("Program segment above .bss in %s", old_name);

=A0=A0=A0=A0=A0 if (NEW_PROGRAM_H (n).p_type =3D=3D PT_LOAD

If I understand there shouldn't be a problem on ppc64le.
But I don't understand a code at all.
