I had the same issue on another ARM SoC. Some research on the topic indicated it was caused by some parts of the system being built with tools configured for 'soft-float' while other parts were compiled with tools configured for 'hard-float'. The results would be incompatible (and would generate this message). I changed my ./configure to include the same options used to build the rest of my BSP: ./configure --disable-8139too --enable-generic CFLAGS='-g -O2 -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9' CPPFLAGS='-g -O2 -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9' CXXFLAGS='-g -O2 -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9' but I got the same error message. BTW - I'm building on the ARM target to take any cross-compilation issues out of the picture. As a workaround, I discovered that if I "touch master/soe_errors.c" when this happens and "make install" again, then it works. Have not had time to go back to it.
