build-many-glibcs.py and Hurd requirement for libtirpc

[Joseph Myers]

Building compilers for i686-gnu with build-many-glibcs.py is currently 
failing when configuring Hurd:

checking for libtirpc... no
configure: error: Package requirements (libtirpc) were not met:

No package 'libtirpc' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables libtirpc_CFLAGS
and libtirpc_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

FAIL: compilers-i686-gnu hurd configure


Since libtirpc depends on libc but the Hurd glibc build requires Hurd 
headers to be installed before glibc is built, this circular dependency is 
a problem.  I'm not sure if this should be fixed in Hurd (passing a fourth 
argument to PKG_CHECK_MODULES to allow libtirpc to be missing, or adding 
some other mechanism to allow it to be missing, when only installing Hurd 
headers), or whether there should be some other workaround in 
build-many-glibcs.py to make Hurd configure think libtirpc is present when 
actually it isn't.

Ah, sorry, it's actually already optional in the makefiles.  I have now
fixed configure.

Thanks for the notification,
