+Fix build issues on ARM with certain toolchains
+
+Some gcc/binutils combinations do not like having a space between
+"-Wa," and the following assembler option, so we simply remove those
+spaces.
+
+However, fixing the configure.in is not sufficient, because libnspr
+absolutely requires the prehistoric autoconf 2.13 to re-generate the
+configure script. So, since the patch to the configure script is not
+horrible, we also patch this script directly.
