The pkg-config tool is automatically passing --static when BR2_STATIC_LIBS
is set (see package/pkgconf/pkgconf.mk), so no need to pass it explicitly
from package .mk files.
Additionally, replace a missed occurrence of $(shell) with backticks.

It is often difficult to know exactly when make will expand the
variable, and usually it can only be expanded after the dependencies
have been built (e.g. pkg-config or the .pc file). Using a backtick
instead makes it very clear that it will be expanded only while
executing the command.
This change is useful for two cases:
1. The per-package staging (and host) directory will be created as part
of the configure step, so any $(shell ...) variable that is used in
the configure step will fail because the directory doesn't exist
yet.
2. 'make printvars' evaluates the variables it prints. It will therefore
trigger a lot of errors from missing .pc files and others. The
backticks, on the other hand, are not expanded, so with this change
the output of 'make printvars' becomes clean again.
This commit contains only the easy changes: replace $(shell ...) with
`...`, and also replace ' with " where needed. Follow-up commits will
tackle the more complicated cases that need additional explanation.
After this change, the following instances of $(shell ...) will remain:
- All assignments that use :=
- All variables that are used in make conditionals (which don't expand
the backticks).
- All variables that only refer to system executables and make
variables that don't change.
- The calls to check-host-* in dependencies.mk, because it is eval'ed.

Changeset f1d3e09 (Build shared libraries only as the default) broke the
nmap package.
nmap builds an internal version of libdnet, and tries to statically link
against it. Of course, this breaks for shared-only builds, since in that
case there is no static lib ever built.
Using an external libdnet is not really an option:
- libdnet comes from dnprogs, from the linux-decnet project;
unfortunately, their build-system is not amenable to
cross-compilation, and is a real pain to deal with;
- nmap's bundled libdnet is anyway heavily modified, which precludes
using an external libdnet.
Fix that by considering libdnet to be a purely internal library, and by
configuring it with --enable-static, always.
nmap's ./configure uses AC_CONFIG_SUBDIRS() to configure the libdnet
sub-directory; AC_CONFIG_SUBDIRS() calls ./configure in all the
sub-directories it is passed as arguments. Unfortunately, it is not
possible to specify extra ./configure arguments whith AC_CONFIG_SUBDIRS.
We are using an autoconf trick, which is, when configuring
sub-directories with AC_CONFIG_SUBDIRS(), it will first try to execute
configure.gnu if it exists, before it fallbacks to running plain
configure. See:
https://www.gnu.org/software/autoconf/manual/autoconf.html#Subdirectories
So, we provide a configure.gnu that is just a wrapper around the real
configure, which sole purpose is to append --enable-static when calling
the real configure.
Note1: since this libdnet is considered a purely internal library, we
also always pass --disable-shared, since it is not needed at all.
Note2: since this libdnet is considered a purely internal library, it
should not be exposed to other packages, and thus nmap does not install
it, neither in target nor in staging, neither static nor shared, which
is what we want.

To be consistent with the recent change of FOO_MAKE_OPT into FOO_MAKE_OPTS,
make the same change for FOO_CONF_OPT.
