This patch adds build-many-glibcs.py support for GNU Hurd. It is
intended for master, where the builds of the i686-gnu configuration
would fail until sufficient support is merged to master, so completing
build-many-glibcs.py coverage of all glibc ABIs and making results
accurately reflect the broken state of builds for Hurd. Using
sthibaul/hurd-builds branch, it reaches the glibc build, which then
falls over with errors starting:
In file included from mutex-init.c:19:0:
../mach/lock-intern.h: In function '__spin_lock_init':
../mach/lock-intern.h:41:13: error: 'LLL_INITIALIZER' undeclared (first use in
this function)
*__lock = LLL_INITIALIZER;
^~~~~~~~~~~~~~~
../mach/lock-intern.h:41:13: note: each undeclared identifier is reported only
once for each function it appears in
../mach/lock-intern.h: In function '__spin_lock':
../mach/lock-intern.h:50:3: error: implicit declaration of function 'lll_lock'
[-Werror=implicit-function-declaration]
lll_lock (__lock, 0);
^~~~~~~~
In file included from mutex-init.c:20:0:
../mach/lowlevellock.h: At top level:
../mach/lowlevellock.h:21:10: fatal error: mach/gnumach.h: No such file or
directory
#include <mach/gnumach.h>
^~~~~~~~~~~~~~~~
Could Hurd people review how this handles building for Hurd, and
indicate whether the above errors indicate problems with these
changes, or simply incompleteness of the build support on the
sthibaul/hurd-builds branch at present?

* scripts/build-many-glibcs.py (Context.add_all_configs): Add
i686-gnu configurations.
(Context.run_builds): Include mig, gnumach and hurd in components
considered.
(Context.checkout): Add mig, gnumach and hurd to components.
(Context.checkout_tar): Add URL mappings for mig, gnumach and
hurd.
(Context.bot_cycle): Check for changes to mig, gnumach and hurd.
(Config.build): Install gnumach headers, build mig and install
hurd headers for 'gnu' OS.
(Config.install_gnumach_headers): New function.
(Config.install_hurd_headers): Likewise.
(Glibc.build_glibc): Do not use /usr for 'gnu' OS. Specifiy MIG
when building for 'gnu' OS.
