It seems that the difference is probably related to a flag --as-needed
/ --no-as-needed.
With the current master, and the change I just pushed, with Buster
_every_ file is now linked to libgpiod
$ ldd ../rtlib/abs_s32.so
linux-vdso.so.1 (0xbeeac000)
/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so =>
/usr/lib/arm-linux-gnueabihf/libarmmem-v7l.so (0xb6f4d000)
libm.so.6 => /lib/arm-linux-gnueabihf/libm.so.6 (0xb6ea3000)
libgpiod.so.2 => /lib/arm-linux-gnueabihf/libgpiod.so.2 (0xb6e8d000)
libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0xb6d3f000)
/lib/ld-linux-armhf.so.3 (0xb6f75000)
It is fairly easy to fix this, by adding the --as-needed flag. The
question then is what is the _right_ thing to do.
I have tested, and the file sizes (of individual files) are exactly the same.
