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.

Like for lingcrypt and openssl, help the configure script to find
zlib installed in STAGING_DIR.
Otherwise, It might find the one installed on the host:
checking how to link with libz... /usr/lib/libz.so -Wl,-rpath -Wl,/usr/lib

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

Since the trailing slash is stripped from $($(PKG)_SITE) by pkg-generic.mk:
$(call DOWNLOAD,$($(PKG)_SITE:/=)/$($(PKG)_SOURCE))
so it is redundant.
This patch removes it from $(PKG)_SITE variable for BR consistency.
