Add build-many-glibcs.py option to strip installed shared libraries.
This patch adds a --strip option to build-many-glibcs.py, to make it strip the installed shared libraries after installation. This is for convenience if you want to compare installed stripped shared libraries before and after a patch that was not meant to result in any code changes: you can run with this option, copy the install/glibcs directory, run again with the patch and compare the */lib* subdirectory contents. (It might make sense for the option to strip libraries in other directories, including stripping debug information from static libraries, with a view to making it possible for a no-generated-code-changes patch to result in completely identical install/glibcs directories, so simplifying comparison, though that may need other build determinism changes, e.g. to build deterministic .a files.) * scripts/build-many-glibcs.py (Context.__init__): Take strip argument. (Glibc.build_glibc): Strip installed shared libraries if requested. (get_parser): Add --strip option. (main): Update Context call.
