[OE-core] [PATCH 1/2] boost: delete the build directory before rebuilding

[Ross Burton]

If there is an existing build directory when do enter do_compile() then delete
it, as it contains the previous build.  If the rebuild was caused because
dependencies have changed we want to ensure that a rebuild actually happens.
