Try adding --enable-maintainer-mode to your configure-options, then all
this is supposed to happen automatically.
Eg. if having edited your <BSP>/Makefile.am (Adding/deleting files)
cd build/<...>/<BSP>
make
will rebuild Makefile.in etc.

[There exist some broken BSPs where this doesn't work.]

Furthermore, it is sufficient to run bootstrap from the directory which
contains the configure.ac/in which is responsibile for the file you have
edited.
Eg. 
[Editing [...]/<BSP>/driver/Makefile.am
cd [...]/<BSP>
<rtems-rootdir>/bootstrap

Try adding --enable-maintainer-mode. 

Then in most cases, running "make" is sufficient. If it doesn't work,
(General exceptions are BSPs containing "tools" - A known general bug in
RTEMS configury - and adding directories - A known general limitation of
the auto*tools), running bootstrap from the directory with the
configure.ac related to the edited Makefile.am should be safe.
