commit: 10e68b02c861ccf2b3adb59d3f0c10dc6b5e3ace Makefile: support
compressed debug info
date: 12 days ago
config: x86_64-randconfig-r032-20200609 (attached as .config)
compiler: gcc-5 (Ubuntu 5.5.0-12ubuntu1) 5.5.0 20171010
reproduce (this is a W=1 build):
git checkout 10e68b02c861ccf2b3adb59d3f0c10dc6b5e3ace
# save the attached .config to linux build tree
make W=1 ARCH=x86_64

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]: Target 'prepare' not remade because of errors.

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.
Hi Fangrui,
Here is the output:
$gcc-5 -v --version
