Because the tools can't cope with them.

The link looks wrong, it includes the absolute path during install time.
+ cmd_modules_install = mkdir -p $(2); mkdir -p $(3); $(OBJCOPY)
--only-keep-debug $@ $(3)/$(@F) && $(OBJCOPY) --strip-debug
--add-gnu-debuglink=$(4)/$(@F) $@ $(2)/$(@F)

Yes, something like:
make modules_install INSTALL_MOD_PATH=debian/build/install_bla
INSTALL_MOD_DEBUGLINK=1
dh_install -p $image --srcdir debian/build/install_bla /boot /lib/modules
if DEBUG
dh_install -p $debug --srcdir debian/build/install_bla /usr/lib/debug
endif
