1. The FS libs/tiff package can make use of liblzma if avaialable. This
fix reverts commit bff1f87ad7. It
checks the CONFIG_PACKAGE_liblzma variable to determine liblzma
and will either pass --enable-lzma or --disable-lzma switch to
configure. For mod-spandsp, +liblzma:liblzma automatically sets
the liblzma dependency flag.
2. Synched to FS git HEAD d35db852a8bcc4fb10e7a8486046aabd45a7f9b2.
