Fix EXPORT_SYMBOL attribute for clang

Clang doesn't have the externally_visible attribute.

    src/pcm/pcm.c:1503:1: error: unknown attribute 'externally_visible' ignored [-Werror,-Wunknown-attributes]
    #define EXPORT_SYMBOL __attribute__((visibility("default"),externally_visible))                                                         ^
