# glibc
#######
# use 2.25 version, not 2.26. Keep the ABI intact!
# endless loop? gawk -f ../scripts/gen-as-const.awk pthread-pi-defines.sym \
# two reasons: clock and artifacts walk backwards or forward in time
# chroot on server with chroot, hard to have an asynchronous clock?
# or glibc is already installed on the system (where not?), so how the
# hell can it be possibly built!
# => oh, this would be cruel.
# or 3rd reason, we have a glibc shim, maybe this one causes some trouble
# => why?
# or libtool fixing, whatever fixing means (https://forums.gentoo.org/viewtopic-t-496052-start-0.html)
# => nope.
# -isystem /usr/includ ein gcc spec? quite likely!

# aftermatch for gcc/binutils

=> this is the cross compiled gcc for i486 inside the chroot, it expects
   its platform dependend stuff in /usr/lib/gcc/i486-unknown-linux-gnu/7.2.0
=> we can temporarily fix this:
ln -s /usr/bin/ld /usr/lib/gcc/i486-unknown-linux-gnu/7.2.0/ld
etc.

# aftermatch for glibc

# bacause pacman cannot set file permissions
chmod u+x /usr/bin/* /lib/*.so*


# in 'real' 486
###############

next round: do those problems persist

error: could not register 'temp' database (wrong or NULL argument passed)

installed binaries have wrong permissions (no execute permission), a pacman issue?
shilly flags? libarchive problem?

later: for inside the chroot
