X-Git-Tag: releases/gcc-12.2.0~141

libstdc++: Add missing prerequisite to generated header [PR106162]

The ${host_builddir}/largefile-config.h header can't be written until
its parent directory has been created, so it needs to have the creation
of that directory as a prerequisite.

libstdc++-v3/ChangeLog:

	PR libstdc++/106162
	* include/Makefile.am (largefile-config.h): Add
	stamp-${host_alias} prerequisite.
	* include/Makefile.in: Regenerate.

(cherry picked from commit 8a6ee426c2be3bd4359520e02c00ec60cac2fece)
