ok, well spoted.


llvm-config exports the flags which has been used to build llvm.

The trigger is:

llvm-toolchain-3.9 (1:3.9.1-16) unstable; urgency=medium
...
  [ Matthias Klose ]
  * Link with --no-keep-files-mapped --no-map-whole-files when using gold.
...
 -- Sylvestre Ledru   Fri, 08 Sep 2017 11:57:07 +0200


But the actual bug is older:
CXXFLAGS_EXTRA += -Wl,-fuse-ld=gold -Wl,--no-keep-files-mapped 
-Wl,--no-map-whole-files

-Wl,-fuse-ld=gold is wrong, this should be -fuse-ld=gold
(it cannot work to tell the linker which linker to use).

Bug#876787: afl: FTBFS /usr/bin/ld: unrecognized option '--no-keep-files-mapped'

[Daniel Stender]

Package: src:afl
Version: 2.50b-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)
Control: block 873404 by -1

AFL begun to FTBFS recently with a clang error:


[+] All set and ready to build.

This seems to be a problem in the build toolchain (this is going to be
reassigned). The same error appears also with clang-4.0 and clang-5.0, thus
blocking the llvm-toolchain update of AFL.
