[OE-core] potential bashism in guile_2.0.13.bb

[Patrick Ohly]

Hello!

verify-bashisms (after some fixing of the script) reports:

/work/iot-ref-kit/openembedded-core/meta/recipes-devtools/guile/guile_2.0.13.bb
 possible bashism in guile_cross_config line 94 ($'...' should be "$(printf '...')"):  
        	echo '#!'`which ${BUILD_SYS}-guile`$' \\\n--no-auto-compile -e main -s\n!#\n(define %guile-build-info '\'\( \
			> ${B}/guile-config.cross


This is for:

guile_cross_config() {
	# this is only for target recipe
	if [ "${PN}" = "guile" ]
	then
	        # Create guile-config returning target values instead of native values
	        install -d ${SYSROOT_DESTDIR}${STAGING_BINDIR_CROSS}
        	echo '#!'`which ${BUILD_SYS}-guile`$' \\\n--no-auto-compile -e main -s\n!#\n(define %guile-build-info '\'\( \
			> ${B}/guile-config.cross

And the resulting guile-config.cross has (when /bin/sh -> /bin/dash):

#!/fast/build/refkit/intel-corei7-64/tmp-glibc/work/corei7-64-refkit-linux/guile/2.0.13-r0/recipe-sysroot-native/usr/bin/x86_64-linux-guile$ \
--no-auto-compile -e main -s
!#
(define %guile-build-info '(
...

This looks rather strange to me and I've no idea how the Linux kernel
will interpret that first shebang line, which literally ends in
...guile$ \

Is the content as intended?

It builds, whatever that means.
