package/libcdaudio: fix build with toolchains lacking C++ support

Browse Source 
When the target toolchain does not support C++, the provided
libcdaudio configure script tries to run a check with the C++
pre-processor provided by the host (/lib/cpp) which may not exist on
some systems.

This issue is fixed by autoreconfiguring the package, as newly
generated configure scripts do not have this issue.

Fixes:
