2020-09-14crossgcc: Fix libcpp to address -Wformat-securityMasanori Ogino
On some systems where the system compiler enables `-Wformat-security -Werror=format-security` options by default, building libcpp fails because the code passes a variable directly as a format string. This change addresses this problem by patching the affected code. Tested with the default compiler of Nixpkgs unstable, GCC 9.3.0 with the options described above enabled by default.
