Is this guaranteed to install glibc-devel before glibc-devel.i686?
There's some weird dependency thing whereby the first glibc installed
ends up getting used by default for something, so if glibc-devel.i686
ends up installed first for whatever reason, everything gets messed
up.  In my own scripts to set up a CentOS build environment I always
install glibc-devel separately first, before installing everything
else.

But since it's all scripted, I haven't seen the actual error in years,
so I forget what it was. :-)

You might consider pro-actively installing glibc-devel separately to
avoid the issue; or you might wait until you get an error so you can
document it properly.

I assume the goal here is to test as much of the build as possible?
Here are additional builddeps I've got in the CentOS packages.  I'm
not positive they're all still needed (or ever were really), so it's
worth taking with a grain of salt:

* Unspecified BuildRequires
transfig
libidn-devel
texi2html
SDL-devel
curl-devel
libX11-devel
ghostscript
texlive-latex
gtk2-devel
libtool
gnutls-devel

* "for the docs"
perl
texinfo
graphviz

* For rombios (I think)
dev86

* "modern compressed kernels"
bzip2-devel
xz-devel

* "libfsimage"
e2fsprogs-devel

* "with_ocaml"
ocaml
ocaml-findlib

* "with_spice"
spice-server-devel
usbredir-devel

Then there's this line, which I'm not sure the best way to translate
into something useful (obvs only for CentOS 7, which has systemd):

BuildRequires: pkgconfig(libsystemd-daemon)

Is that helpful?
