Python uses AC_RUN_IFELSE to determine the byte order for floats and doubles,
and falls back onto "I don't know" if it can't run code. This results in
crippled floating point numbers in Python, and the regression tests fail.
Instead of running code, take a macro from autoconf-archive which compiles C
with a special double in which has an ASCII representation, and then greps the
binary to identify the format.

Add a PACKAGECONFIG for profile-guided-optimisation, and default to whether
qemu-usermode is available.
Move --enable-optimizations to the pgo optimisation as all this currently does
is use the PGO rules, causing a performance hit if PGO isn't actually used.

We're repeating the same make invocation over and over, twice without setting
OPT=${CFLAGS} which doesn't seem right.
Centralise the make invocation to clean up the tasks.

This patch improves the create_manifest script by making it
use PYTHON_MAJMIN instead of hard coded paths containing the
version number when looking at the necessary modules for
every package, the script should now be independent of the
python(3) version on which were working

There is no good reason to loop 10 times on the test since the profile
optimisation won't change between runs, we don't need/want a statistical
average. This is just burning cpu cycles, just make 1 run.

Since `6146b8c glibc: Disable crypt support in glibc' in oe-core,
python2/3 could not find symbol crypt which caused import crypt failed.

Add virtual/crypt to DEPENDS, and python's build system (setup.py)
will search libcrypt.so in recipe-sysroot and add `-lcrypt' if it
exists.

Enable profile guided optimization (pgo) for python3. Enabling pgo in
python is generally as simple as invoking the target profile-opt which:
- builds python binaries with profile instrumentation enabled,
- runs a specific profile task using that python to get the profile
data and,
- feeds the compiler with this profile data and rebuilds python.
This change invokes qemu-user for the second step of running a profile
task using target python. Depending on how long profile task takes to
run, this might add a significant time to compilation (which would be
true for native builds too). The default profile task can be changed by
the users depending on what makes sense for their use case (or can be
left empty). In case qemu-user isn't supported, profile task won't be run.

Currently, $HOME/.local is being added into sys.path in the Python SDK
causing subtle host contamination. Suppress this by exporting
PYTHONNOUSERSITE = "1" as documented in PEP 370.
This issue occurred in the past for python*-native and was fixed
similarly in OE-core commit 8fe9fb4d5a61dcbcb3fc5b9ee0234cc135af873f
("python*native.bbclass: suppress user site dirs").

The python3 installation in the SDK did not include the minimum set
of modules to be functional, particularly in the case where Python
is brought in through dependencies. Rather than requiring the user
to explicitly add the modules, it's better to pull in the modules
through RRECOMMENDS. Note that the Python 2 recipe already does
this.
