texlive-core configure process ends with error while trying to determine floating-point types endianness in the cairo library subdirectory if LTO is required: configure: error: Unknown float word ordering. You need to manually preset ax_cv_c_float_words_bigendian=no (or yes) according to your system. It's a long standing bug (at least 2 years)... A proposal patch allow to temporary disable LTO during cairo configuration. Reproducible: Always Steps to Reproduce: 1. Make sure '-flto' is set in compilation flags 2. Try to emerge texlive-core Actual Results: configuration of cairo libray fails Expected Results: Build to succeed
