[OE-core] [PATCH] alsa-tools/autotools: Ensure that aclocal files can be present with AUTOTOOLS_COPYACLOCAL variable

[Richard Purdie]

Introduce a AUTOTOOLS_COPYACLOCAL variable which forces the copy of the aclocal
files even when a configure.ac/.in file isn't present.

Use this new feature in alsa-tools.
