Subject: external toolchain: check BR2_INSTALL_LIBSTDCPP
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fad3b5a7bee8ce6dd1cf17f230de693d8ed9230f;p=buildroot.git

external toolchain: check BR2_INSTALL_LIBSTDCPP

Verify that the value of BR2_INSTALL_LIBSTDCPP set by the user in the
Buildroot configuration really matches the external toolchain
capabilities by checking that a C++ cross-compiler is available.
