Hi Thomas,

> BR2_TOOLCHAIN_EXTERNAL_GCC_4_9=y
> BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_14=y
> BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
> # BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
> BR2_TOOLCHAIN_EXTERNAL_CXX=y
> BR2_INIT_NONE=y
> BR2_SYSTEM_BIN_SH_NONE=y
> # BR2_PACKAGE_BUSYBOX is not set
> BR2_PACKAGE_LTP_TESTSUITE=y
> # BR2_TARGET_ROOTFS_TAR is not set

> It has FTS disabled:

> $ grep FTS output/staging/usr/include/bits/uClibc_config.h
> #undef __UCLIBC_HAS_FTS__

> And it builds perfectly fine.
Thanks for a research (I'll do more testing next time, not just reviewing)!
Actually testing it, it's really ok, due these lines in
package/ltp-testsuite/ltp-testsuite.mk:

# Requires uClibc fts and bessel support, normally not enabled
ifeq ($(BR2_TOOLCHAIN_USES_UCLIBC),y)
define LTP_TESTSUITE_REMOVE_UNSUPPORTED
	rm -rf $(@D)/testcases/kernel/controllers/cpuset/
	rm -rf $(@D)/testcases/misc/math/float/bessel/
	rm -f $(@D)/testcases/misc/math/float/float_bessel.c
endef
LTP_TESTSUITE_POST_PATCH_HOOKS += LTP_TESTSUITE_REMOVE_UNSUPPORTED
endif

We can either remove deleting testcases/kernel/controllers/cpuset/ as part of
this patchset, or simply wait for next update (planning for the start of the
second week in the May [1]), I'd remove it during the update.

Kind regards,
Petr
