  48 # if you want to understand a bit more in the case of glibc, shared libs do fall
  49 # in the "shared" category (there, you can see the object requirement of PIE
  50 # static-PIE, etc etc).

  52 # libgcc, and the glibc itself, namely you have to handle that with your linker
  53 # (binutils ld has --{start,end}-group, or YOU USUALLY HAVE TO REPEAT THE
  54 # LIBRARY FILES (XXX: DOES NOT WORK WITH OBJECT FILES) ON THE LINK COMMAND LINE
  55 # UNTIL YOU BREAK THE CIRCULAR DEPENDENCY.
  56 # We want full pathnames.
