xtensa: fix endianness support To build uClibc correctly we need correct endianness selected in the crosstool-NG. Xtensa cores may be little- or big-endian, but this property is static. The toolchain knows the core endianness and doesn't need options to select it. Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to the TARGET_CFLAGS, as it's not supported by gcc. Specify empty CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the TARGET_LDFLAGS as they are ignored. Select big-endian in the example xtensa-unknown-linux-uclibc configuration. This fixes uClibc toolchain build for little-endian cores. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> 2016-10-24 21:48:57 +00:00			`CT_ARCH_BE=y`
samples: add target CFLAGS to xtensa-unknown-linux-uclibc Add -mlongcalls and -mtext-section-literals to target CFLAGS. Target libraries built with these flags have great call range, useful for linux applications.
