If LOCAL_CCACHE is set to the full path of ccache on the build host
it will be used for early stage host package builds, eg make and ccache
at the moment.
By default it uses a separate cache dir (.ccache-local) so that it
doesn't interfere with our ccache (which is typically a different
version). The location can be changed by setting LOCAL_CCACHE_DIR

This is needed for host packages built in very early stages,
before host-cc (which typically uses ccache) is available.
Set CC/CXX to LOCAL_CC/CXX in this case.

Default linker can be set with DEFAULT_LINKER in options.
Packages can influence linker selection both by positive and/or
negative PKG_BUILD_FLAGS, eg +bfd or -gold.
Positive build flags take priority over the default linker so eg
DEFAULT_LINKER="gold" and PKG_BUILD_FLAGS="+bfd" will select bfd.
Negative flags mean a specific linker should not be used, eg -gold
prevents using gold.
If the default linker is disabled via a build flag then any other
available linker will be used.
Optional linkers like gold have to be enabled with eg GOLD_SUPPORT="yes"
in options. If an optional linker is not enabled it won't be a candidate
for linker selection. So eg "+mold" will have no effect if MOLD_SUPPORT
isn't set to "yes".

Timing detail reporting can be enabled by setting
TRACE_BUILD_TIMING=1
This enables timestamping collecting at various build stages so we
can easily analyze how long eg configure, make/build, install etc
steps take.

This function can be used on "autotools" and "configure" packages.
Use libtool_remove_rpath() to remove hardcode rpath when --disable-rpath
is not supported by "configure".
usage: `libtool_remove_rpath libtool`
If there are multiple libtool scripts or they are in subdirectories,
then you may need to run this function using the path to libtool or run
the function multiple times.
If binaries and shared objects installed by the package to target have
incorrect or system libraries then this function can be used. After
using the function, these example command below should NOT have a
RPATH/RUNPATH.
e.g. (before using the fucntion)
$ readelf --dynamic ${filename} | grep PATH
RPATH Library runpath: [.....]
RUNPATH Library runpath: [.....]
Before using this function; check if the package supports
--disable-rpath (and that it works.) Work with upstream and have a
working --disable-rpath added to the package.
