[OE-core] [PATCH] guile: fix a bashism

[liu.ming50 at gmail.com]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

A following flaw was detected by verify-bashisms script:
......
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
......

Fixed by removing $'...' from echo command, using a printf instead.
