Giacomo Tesio f598a59d81 gcc: remove `--posixly`, add `-9` 
The GCC option `--posixly` was introduced to enable the compilation
of POSIX code in Jehanne, assuming that building native C code
would have been the default.

However since

- GCC is itself a POSIX program and most programmers that use it
  assume a POSIX environment
- GCC is used as a cross compiler to build Jehanne from POSIX systems
- C++ will never be native in Jehanne (too much complexity for a
  system that want to be simple) and thus will always require a
  POSIX environment to build POSIX C++ code

I decided to invert the logic.

Thus now by default GCC, by default, will build POSIX programs,
loading required libraries and headers from /posix subdirectories.

The new option `-9` will remove such POSIX stuff when compiling
native C programs.

Giacomo Tesio 7278b664fc gcc: fix `--posixly` management in cross compiler 2020-09-02 18:52:23 +02:00
Giacomo Tesio 8d419405cb gcc native: remove cross/native.sh and unused patches in cross/pkgs/gcc/patch 
Apparently we can use the patches created for the cross compiler.

cross/native.sh has been moved in cross/pkgs/gcc/build.sh to get some
coherence among the packages (in the hope of writing a reasonable
package manager in the future).
