The bind package exhibits gcc bug 101737 when built for the SH4
architecture with optimization enabled, which causes a build failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_101737=y.
To achieve this we need to correct the override of CFLAGS by using:
BIND_CONF_OPTS += CFLAGS="$(BIND_CFLAGS)"
instead of:
BIND_CONF_ENV = BUILD_CFLAGS"$(BIND_CFLAGS)"
since the latter doesn't work as expected and doesn't override CFLAGS.
