-+ Added a hack for gcc-specs-* in toolchain-funcs.eclass and _filter-hardened in flag-o-matic.eclass
-+ to support older hardened GCC patches and we don't need to change the code on gcc-specs-* and _filter-hardened.
-+ This will add some unsupported upstream commands options as -nopie and -nonow.

-+ ESP_LINK_PIE_CHECK_SPEC check for -pie, -p, -pg, -profile and -static.
-+ ENABLE_CRTBEGINP add support for crtbeginP.o, build -static with -fPIE or -fpie.
