Hmm...I wonder if the feature detection is incomplete? I suspect it's
possible to not depend on zlib.
make[2]: *** [scripts/Makefile.build:277: scripts/mod/empty.o] Error 1
make[2]: Target '__build' not remade because of errors.
make[1]: *** [Makefile:1169: prepare0] Error 2
make[1]: Target 'prepare' not remade because of errors.
make: *** [Makefile:185: __sub-make] Error 2
The output of gcc-5 -v --version on that machine may help. The
convoluted gcc_cv_ld_compress_de logic in gcc/configure.ac may be
related, but I can't find any mistake that our
CONFIG_DEBUG_INFO_COMPRESSED conditions may make.
