How to install data / lib in more than 1 place?

[Georg-Johann Lay]

Hi, I have an automake file with rules for a lib like this:
__install_dir = $(prefix)/avr/lib/$(AVR_INSTALL_DIR)

avrdir = $(__install_dir)
avrlibdir = $(__install_dir)

avr_LIBRARIES = libdev.a
nodist_libdev_a_SOURCES = ...

What would be the recommended way to install libdev.a also in several 
sub-folders like in $(avrlibdir)/dir1 $(avrlibdir)/dir2 etc.?

Currently, there are a bunch of SUBDIRS which are all generating the 
same binary, it's just that they are installed in a slightly different 
place.

Same for data:

avr_DATA = crt1.o

Would one just

avr1dir = $(avrdir)/xdir

avr1_DATA = crt1.o

Thanks for any insights,

Johann
