packages: use backtick instead of $(shell ...) make function 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.

package/nmap: fix shared-only build 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.
