There was a problem hiding this comment.
ACK faef344, tested on Linux Mint 20.2 (x86_64):
$ ./configure 2>&1 | grep -i fuzz
with fuzz binary = yes
CPPFLAGS = -fmacro-prefix-map=$(abs_top_srcdir)=. -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -DHAVE_BUILD_INFO -DPROVIDE_FUZZ_MAIN_FUNCTION
$ ./configure --disable-fuzz-binary 2>&1 | grep -i fuzz
configure: running /bin/bash ./configure --disable-option-checking '--prefix=/usr/local' '--disable-fuzz-binary' '--disable-shared' '--with-pic' '--enable-benchmark=no' '--enable-module-recovery' '--enable-module-schnorrsig' '--enable-experimental' --cache-file=/dev/null --srcdir=.
with fuzz binary = no
CPPFLAGS = -fmacro-prefix-map=$(abs_top_srcdir)=. -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -DHAVE_BUILD_INFO -DPROVIDE_FUZZ_MAIN_FUNCTIONBtw, it looks like the setting of the -DPROVIDE_FUZZ_MAIN_FUNCTION flag should be revisited.

enable_fuzzon current master does not mean the the fuzz binary is not compiled. This is confusion, so fix it.enable_fuzztoggles compilation flags for fuzzing and disables all other target. There is no need to print this in the configure result, because the compilation flags are already printed. Also, all other targets are already printed asno.enable_fuzz_binarydoes what it says it does and is currently not printed. So print it.
