minidebuginfo: Fix stripping/debuginfo
gdb/doc/
2013-09-11 Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.texinfo (MiniDebugInfo): Prepare file debug and use it to create
mini_debuginfo. Strip binary before adding mini_debuginfo to it.
gdb/testsuite/
2013-09-11 Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.base/gnu-debugdata.exp (objcopy 1): Move it lower and use only
debug part of the binary.
