openjdk: autools not to override B var

${B} is set before autotools and thus is overrided
by autotools.  Some of the patches within icedtea are
expected to be patched against ${S}/build (during
do_configure() phase).  As autotools to change B
= "${WORKDIR}/build", so this causes some patches failed
to apply and hence breaks do_configure() with the following
errors:

| patching file openjdk/jdk/make/tools/src/build/tools/generatecurrencydata/GenerateCurrencyData.java
| can't find file to patch at input line 13
| Perhaps you used the wrong -p or --strip option?
