You have some setup issues. From config.log your Linaro GCC seems broken:
configure:3815: checking whether the C compiler works
configure:3837: arm-linux-gnueabihf-gcc -march=armv7-a -marm -mfpu=neon -mfloat-abi=hard --sysroot=/home/dcastelow/sdk5/arago/tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/libtool-cross/2.4.6-r0/recipe-sysroot -isystem/home/dcastelow/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/include -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/home/dcastelow/sdk5/arago/tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/libtool-cross/2.4.6-r0=/usr/src/debug/libtool-cross/2.4.6-r0 -fdebug-prefix-map=/home/dcastelow/sdk5/arago/tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/libtool-cross/2.4.6-r0/recipe-sysroot-native= -fdebug-prefix-map=/home/dcastelow/sdk5/arago/tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/libtool-cross/2.4.6-r0/recipe-sysroot= -isystem/home/dcastelow/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/include -L/home/dcastelow/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/lib -Wl,-rpath-link,/home/dcastelow/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/lib -Wl,-O1 -Wl,--hash-style=gnu conftest.c >&5

configure:3884: error: in `/home/dcastelow/sdk5/arago/tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/libtool-cross/2.4.6-r0/build':
configure:3886: error: C compiler cannot create executables
So, since your Linaro GCC cannot cross-compile a simple program, it fails at
the first dependency that uses it, which happens to be libtool-cross.
Please resolve your setup problems and everything will work w/o any
modifications to recipes. Thanks.
