build: bison: build nolimips with bison

In order to avoid conflicts between the LRDE bison version needed to
build nolimips and the last bison version install on the host machine,
this commit gets bison from the LRDE tarball, build it and use it.

This commit fixes also some ugly tabulations and trailing whitespaces.
