Details

The configure/build system as it stands mostly allows separate compliation, when you run configure from a different directory, but fails in subtle ways. In particular, cpu-type detection and bundling fail. This small patch fixes the various issues. It also removes some related excess quoting that ended up un-quoting paths instead of quoting them (""/path/"").

Obviously it is up to you whether you actually want to support this, but if you don't, it would be nice if it did a check during configure and complained if $PWD != $ROOT_DIR.

Hmm, it's not that easy with these four:
+ $(Q)cp "$(ROOT_DIR)/bin/baseset/"*.grf "$(BASESET_DIR)/"
+ $(Q)cp "$(ROOT_DIR)/bin/baseset/"*.obg "$(BASESET_DIR)/"
+ $(Q)cp "$(ROOT_DIR)/bin/baseset/"*.obs "$(BASESET_DIR)/"
+ $(Q)cp "$(ROOT_DIR)/bin/baseset/"*.obm "$(BASESET_DIR)/"

Depending on whether GRFcodec is installed or not, they are build from (real) sources or taken as it from the repository.

The readme claims that using grfcodec will "leave the repository in a modified state" and "modify the base file set." One solution then would be to update Makefile.grf.in to make this actually true, and put the files in $ROOT_DIR/bin rather than $BIN_DIR. Alternatively, bundle could copy from $ROOT_DIR and then copy any addition files from $BIN_DIR if they exist, overwriting the originals.
