* [BOX32] More wrapped libs and 32bits fixes and imrpovments

* [BOX32] Added some 32bits tests

* [BOX32] Try to enable some Box32 build and test on the CI

* [BOX32] Disable Box32 testing on CI platform that use qemu

* [BOX32] Another attempt to disable Box32 testing on CI platform that use qemu

* [BOX32] Small fix for another attempt to disable Box32 testing on CI platform that use qemu

* [BOX32] Yet another fix for another attempt to disable Box32 testing on CI platform that use qemu

* [BOX32] Fixed a typo in CI script

* [BOX32] Better scratch alighnment and enabled more tests

* [BOX32] Added (partial) wrapped 32bits librt

* [BOX32] Enabled a few more 32bits tests

* [BOX32] For ld_lib_path for both CppThreads tests

* [BOX32] [ANDROID] Some Fixes for Android Build

* [BOX32] Still need to disable cppThread_32bits test on CI for some reason

* [BOX32] [ANDROID] One More Fix for Android Build That I forgotten to … (#1752)

* [BOX32] [ANDROID] One More Fix for Android Build That I forgotten to push before

* [BOX32] [ANDROID] Try to Create __libc_init

* [BOX32] [ANDROID] Try to disable NEEDED_LIBS for now (libdl is not wrapped)

* [BOX32] Updated generated files

* [BOX32] Added 32bits context functions

* [BOX32] Added 32bits signal handling

* [BOX32] Added some missing 32bits elfloader functions

* [BOX32] Fix build on x86_64 machine

* [BOX32] Better fix for x86_64 build

* [BOX32] Actually added missing libs, and re-enabled cppThreads_32bits test

* [BOX32] Added wrapped 32bits libdl

* [BOX32] Try to re-enabled Box32 test on CI for ARM64 builds

* [BOX32] fine-tuning Box32 test on CI for ARM64 builds

* [BOX32] More fine-tuning to Box32 test on CI for ARM64 builds

* [BOX32] Enabled Box32 test on CI for LA64 and RV64 builds too

* [BOX32] re-Disabled Box32 test on CI for LA64 and RV64 builds, not working for now

* [BOX32] Temporarily disabled cppThreads_32bits test on CI
