15+/* This file will add -fstack-protector-all, -fstack-check, -fPIE, -pie and -z now
16+ as default if the defines and the spec allow it.
17+ Added a hack for gcc-specs-* in toolchain-funcs.eclass and _filter-hardened in flag-o-matic.eclass
18+ to support older hardened GCC patches and we don't need to change the code on gcc-specs-* and _filter-hardened.
19+ This will add some unsupported upstream commands options as -nopie and -nonow.
20+ -D__KERNEL__ is added so we don't have -fPIE, -pie and -fstack-protector-all and -fstack-check when building kernels.
21+ ESP_CC1_SPEC is added to CC1_SPEC.
22+ ESP_CC1_STRICT_OVERFLOW_SPEC is added so we don't disable the strict-overflow check.
23+ ESP_LINK_PIE_CHECK_SPEC check for -pie, -p, -pg, -profile and -static.
24+ ENABLE_CRTBEGINP add support for crtbeginP.o, build -static with -fPIE or -fpie.
