Hello everybody,

building lvm2 with a shell other than bash fails:

% make -C tools/ command-count.h
make: Entering directory 'lvm2/tools'
    [GEN] cmds.h
/bin/dash: 1: set: Illegal option -o pipefail
    [GEN] command-lines-input.h
/bin/dash: 1: set: Illegal option -o pipefail
    [GEN] command-count.h
/bin/dash: 1: set: Illegal option -o pipefail
make: *** [Makefile:170: command-count.h] Error 2
make: Leaving directory 'lvm2/tools'

Please fix bashism in Makefile. Thanks!
