You don't need bjam, just get vanilla jam 2.5.

For example without the added grist (just like I archive the lib within the jam file the object is built)? I understand that the rule Objects adds those grists to provide a unique object and I do not want to lose this feature.
Yes. Use FGristFiles to add current location grist, i.e.
LibraryFromObjects component$(SUFLIB) : [ FGristFiles $(OBJS) ] ;
If those OBJS aren't in the current location then you could do it the
SubDir TOP location of objs ;
OBJS = [ FGristFiles $(OBJS) ] ;
SubDir TOP here ;
LibraryFromObjects component$(SUFLIB) : $(OBJS) ;
But why don't you just put component1.lib in component1 directory
where it's files are? I.e.
SubDir TOP component1 ;
SRC = [ Glob [ FDirName $(SUBDIR) src : *.c ] ; # scan for sources
SEARCH_SOURCE = src ; # tell jam to look here for them
Library component1 : $(SRC:BS) ; # build lib from srcs
Don't put a jamfile in 'src', just make a jamfile for each library.
SEARCH_SOURCE will tell jam to look in the 'src' sub folder for the
sources plus grist the sources for this library.
