configure: add -pkg-config option to control pkg-config usage
Currently, for host builds, pkg-config usage is autodetected based
on it's availability in the mkspec or the PATH. For xcompile builds,
pkg-config is disabled unless -force-pkg-config is passed.
-force-pkg-config is poorly named since it doesn't reflect the fact
that it applies only to xplatform builds. It is in fact the only way to
enable pkg-config in xcompile builds. And when passed, it doesn't actually
force anything since all it does is check env variables. To add to the
confusion, it prints a warning even if the env variables are setup correctly.
This patch remedies the situation. It adds (-no)-pkg-config. The flag works
for both host and xcompile builds.
By default, the value is 'auto'. In this mode, it will try try to detect pkg-config
from the path. If found, it will be used. For xcompiled builds, we use some heuristics
to determine if the pkg-config is actually usable:
1. if -sysroot is not set and the environment variables PKG_CONFIG_LIBDIR or
PKG_CONFIG_SYSROOT_DIR are not set, we disable pkg-config.
2. if -sysroot is set, then we setup PKG_CONFIG_LIBDIR and PKG_CONFIG_SYSROOT_DIR
automatically (provided $SYSROOT/usr/lib/pkgconfig exists).
If the value is 'yes', configure will error if it's heuristics fail to detect a usable
pkg-config.
If the value is 'no', pkg-config usage is disabled.
If the value is 'force', configure will skip it's heuristics and use pkg-config anyway.
This mode is useful, for example, when compiling for 32-bit on 64-bit systems.
This change also removes references to PKG_CONFIG_SYSROOT (PKG_CONFIG_SYSROOT_DIR
is the correct environment variable).
