When using uclibc libdevmapper.so was calling dm_task_get_info_base()
function recursively, leading to segmentation fault. This was
happening because uclibc linker loader just takes first existing
'dm_task_get_info' (which is 'dm_task_get_info_base') symbol in elf
binary, instead of default version.
Add upstreamable lvm2 patch [1], which introduces
--enable-symvers[=STYLE] switch. Use that switch to disable symbol
versions, as we do not plan to support binaries compiled against
old libdevmapper library.
Fixes bug #10781.
