news/libcanlock: Update to 3.2.0

Changelog
=========

3.2.0      2020-05-11
           Support for pkg-config with option "--enable-pc-files" added
            (Default behaviour is unchanged). This option installs the
            pkg-config file "libcanlock-3.pc". The standard option
            "--with-pkgconfigdir" can be used to specify the target \ 
directory
           Shared library no longer exports internal symbols, if possible
            (using #pragma GCC visibility). Library API and ABI are fully
            compatible if no undocumented functions are used.
           Build system: Distributed autotools files updated
