From a23edf42678c0b47705b6f2b3827cce175539330 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Mon, 21 Apr 2025 11:18:43 -0700 Subject: gcc: Add CC_GCC_LIBSTDCXX_TARGET_CXXFLAGS This parallels the newlib-nano setting, NEWLIB_NANO_GCC_LIBSTDCXX_TARGET_CXXFLAGS, and provides a place to specify options that control how libstdc++ is build, such as -fno-exceptions.
