I am confused, because the current ltp-testsuite package seems to build
properly with uClibc that doesn't have FTS support enabled. I just
built the following configuration:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2019.02-rc1.tar.bz2"
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.

Best regards,

Thomas
