Subject: build: propagate $SHELL to makeinfo-wrapper.sh
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff91b77b0f0e6f78a44d45ed3837a6094a694950;p=thirdparty%2Fcoreutils.git

build: propagate $SHELL to makeinfo-wrapper.sh

A user that had an environment with SHELL=/usr/bin/fish
reported the following when trying to build info docs:

  build-aux/missing (line 4): Unsupported use of '='. In fish

* doc/local.mk: Propagate make's SHELL to our
makeinfo wrapper, so that the substituted ${SHELL}
uses a compatible shell from the Makefile.
