[dm-devel] [PATCH] tests: fix quoting of CFLAGS in Makefile

[Sam James]

Otherwise, when CFLAGS/CPPFLAGS have multiple entries (like "-O2 -pipe"), we
get an error:
```
make[1]: Entering directory '/var/tmp/portage/sys-fs/multipath-tools-0.9.4/work/multipath-tools-0.9.4/tests'
/bin/sh: line 1: -pipe: command not found
make[1]: *** [Makefile:115: libmultipath.so.0] Error 127
make[1]: *** Waiting for unfinished jobs....
```
