[sb2] Fix make depency graph resolving. Fixes JB#52244

See merge request !44

The output directory has to exist before make creates the dependency
graph or the build may break when CWD is not $(SCRDIR).
This for example caused in case of rule_tree.o make to have to receipes for the same file one with -fPIC
and one without -fPIC breaking PIC and breaking building libsb2.so on x86_64.

Fix host-gcc use

See merge request !41

It has been obsoleted since commit
1b7fb2f6 (Create /usr/bin "autorules"
via init.lua) and commit c85c5397
(Top-level Makefile: Install rule_constants.lua) stopped installing it.

This fixes commit dbcf9d60 (support
different gcc search patchs)

Initially, my_envp equals to *new_envp, then it is modified. Those
modifications are lost when *new_envp is used after that.

The (possibly) discarted modifications to env. variables affect
SBOX_DISABLE_MAPPING, SBOX_DISABLE_ARGVENVP and __SB2_REAL_BINARYNAME.

Regarding SBOX_DISABLE_MAPPING, consider a host executable being
executed by sb2 and trying to execute another host executable. With
mapping not disabled, the other executable may be mapped to a different
executable under target/tools root instead. In most cases this is likely
to happen unnoticed. It breaks when there is an incompatibility between
those, e.g., when the host executable is a GCC compiler trying to
execute some of its internal tools - an i486 host compiler may end up
executing an arm assembler this way.

Trying to explain why *new_envp was used here, I don't believe it was a
typo. At the same time I don't believe it was intentional to change the
logic this way. I can't think of a reason to discard changes to the
afforementioned env. vars. To me it seems inevitable to keep them set.
Also, change was introduced with commit
3f042f36 (Execs: Postprocess native
dynamic binaries with C code) whose only objective seems to be
reimplementation of some Lua code in C.  Maybe it was done to deal with
some compiler bug and no one noticed it breaks things, as this only
breaks in rather special cases like the one mentioned above.

[sb2] Add mapping for aligned workspace mount points. JB#49476

See merge request !37

Applies when sb2 is used under the SDK build engine.

Workspace directories used to be mounted at fixed paths under /home.
Now the mount point paths are chosen in a way that they align with the
source paths on host (e.g. "/home/user/work" -> "/home/user/work",
"C:\Users\user\work" -> "/c/Users/user/work").

/dev/full was previously not explicitly handled, it was just reported
as read-only or ignored (in case the user was root).
But it needs to be forward to the host to behave like it does there
e.g. saying there is no space left.

[scratchbox2] Fix behaivior of /dev/full in scratchbox2. Contributes
to JB#44353
Signed-off-by: Björn Bidar <bjorn.bidar@jolla.com>

If using -Wl,-r to manually pass the option LD would error out and say:
/usr/bin/ld: -r and -pie may not be used together
when using a compiler that enables -fPIE by default.
By using just -r and telling the compiler to pass it to the linker on
its on to the linker it avoids this error.
