On a system without ccache, f you:
INHERIT += "ccache"
bitbake libtool-cross
<remove INHERIT>
bitbake apmd
then it fails due to being unable to find ccache. The references to ccache are
coded into libtool-cross but the sstate checksum doesn't reflect this due to the
way the class is coded (output should be the same regardless).
The simplest solution is to remove references to ccache from the libtool script.
The output then works regardless of whether ccache is present or not. The
libtool-cross script is only used in a handful of cases (most of the time its
dynamically generated by autoconf) so any performance issue is minor.
