0001-configure.ac-workaround-quoting-issues.patch

The following code doesn't work in dash (note ^C - I've pressed Ctrl+C
here):

$ BROWSER_PLUGIN_DIR="${BROWSER_PLUGIN_DIR:-"\${libdir}/mozilla/plugins"}"
> ^C
$

Therefore I get the following configure error:

checking for GTKDOC_DEPS... yes
checking for xsltproc... (cached) /usr/bin/xsltproc
checking whether gcc understands -Wall... yes
checking what warning flags to pass to the C compiler...  -Wall
checking what language compliance flags to pass to the C compiler... 
./configure: 2: ./configure: Syntax error: Unterminated quoted string


Autoconf manual [1] suggests: "Perhaps the easiest way to work around quoting issues in a manner portable to all shells is to place the results in a temporary variable, then use ‘$t’ as the value, rather than trying to inline the expression needing quoting." An indeed that works:

$ t="\${libdir}/mozilla/plugins"
$ echo "${BROWSER_PLUGIN_DIR:-$t}"
${libdir}/mozilla/plugins
$

But I suggest to replace the problematic code with conditional statement.
