Sertonix fcb89662e0 chreipl-fcp-mpath: Use sha256sum -c instead of --check 
The --check long option is not available in some sha256sum
implementations like busybox.

## Utility
#
# Utilities for the debug feature of chreipl-fcp-mpath-common.sh.
#
# When `chreipl-fcp-mpath` is built with D=1 (default is D=0), each run
# of one of the helper scripts will create a debug log in $(DEBUGOUTDIR)
# (default: /run/udev) which among other things contains the complete shell
# trace of that script run, with some added information that would not be
# inspectable otherwise with just the trace.
#
# There is currently no way of enabling/disabling this at runtime.
#
# chreipl-fcp-mpath-common.sh defines debug log file name as
# "chreiplzfcpmp-${debug_trace_tag}-${SEQNUM:-0}.XXXXXXXXXX" where SEQNUM is a
# udev rule environment variable and each X is replaced with some [[:alnum:]]
# by mktemp. For a definition of `debug_trace_tag`, please see the comments
# in the source.
#
# The following targets can be used for some simple access and filtering of the
# logs during development.
DEBUG_LOG_GLOB = $(DEBUGOUTDIR)/chreiplzfcpmp-[[:digit:]][[:digit:]][[:alpha:]][[:alpha:]][[:alpha:]][[:alpha:]]-+([[:digit:]]).[[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]]
