I have spent the afternoon figuring out the minimal set of static libraries 
needed to get all the tests for binutils to pass.  What I have is:

libc.a           (7)
libc_nonshared.a (many)
libdl.a          (7)
libm.a           (2) (LTO)
libz.a           (7)

The numbers above indicate the number of tests that fail if only that library is 
removed.  I did this in the chroot environment at Section 6.13.
