As found out by Yann [1], binutils will use its bundled copy of zlib,
whether it is already provided by the system or not, and unless
explicitly told to use the system zlib with --with-system-zlib, which
is available since version 2.21 and
700d40ca16
This will fix the following build failure with oprofile when compiling
in a static configuration where zlib is not enabled:
checking for bfd_openr in -lbfd... no
checking for compress in -lz... no
configure: error: libz library not found; required by libbfd
As found out by Arnout [1], this fails infrequently because static is
already pretty rare, but in addition zlib is almost always selected by
some other package.
