config.log claims invocation is FLAGS=foo bar when really FLAGS='foo bar'

[Kevin Brubeck Unhammer]

Tested with GNU Autoconf 2.69.

To reproduce, open any autoconf-using project and run:

$ ./configure FLAGS='foo bar' >/dev/null && grep -m1 /configure config.log
  $ ./configure FLAGS=foo bar

Expected output:
  $ ./configure "FLAGS='foo bar'"


I know the shell interprets the quotes etc., but it's possible to work
around that; e.g.

C=''
for i in "$@"; do
    i=$(echo "$i" | sed 's/\\/\\\\/g; s/\"/\\\"/g')
    C="$C \"$i\""
done
echo "$C"
