Never tested but we are building it and the patch is needed for that.

The goal of this was disabling building shared libraries and linking to them.
Cleaner way would be simply change --enable-static_link to do the same.
Right now you can't just build static libraries, even
with --enable-static_link shared lib is being built:
klcc -static -shared -Wl,-soname,libdevmapper.so.1.02 \
-O2 -fno-strict-aliasing -fwrapv -march=x86-64 -gdwarf-2 -g2 -fPIC
-Wall -Wundef -Wshadow -Wcast-align -Wwrite-strings -Wmissing-prototypes
-Wmissing-declarations -Wnested-externs -Winline -O2 -fno-strict-aliasing
-fwrapv -march=x86-64 -gdwarf-2 -g2 -Wl,--as-needed
-Wl,--version-script,.export.sym -L../lib/ioctl datastruct/bitset.o
datastruct/hash.o libdm-common.o libdm-file.o libdm-deptree.o libdm-string.o
libdm-report.o mm/dbg_malloc.o mm/pool.o regex/matcher.o regex/parse_rx.o
regex/ttree.o ioctl/libdm-iface.o -o ioctl/libdevmapper.so
Is changing --enable-static_link to disable building shared libs a fine

AFAIK the problem was that it was prefering system wide header over local in
package. So when building new version of device-mapper old system include
header was used.

It doesn't fix anything. It merely replaces functions with these available in
klibc so you can build device-mapper against klibc.
