I am afraid you did not suffer pain from it, the most related message
with do_configure failure is config.log. Take a example, as my previous
commit [grub/grub-efi: fix unrecognized command line option
'-pipe-Wno-error' in CFLAGS]
It takes me hours to reproduce grub/grub-efi build faiure (only
happen while DEBUG_BUILD = "1"), and from log.do_configure, I can't
tell the root cause

configure: error: in
`TOPDIR/tmp-glibc/work/i586-wrs-linux/grub/2.02-r0/build':

But from config.log, I got more detail '-pipe-Wno-error'
which helps me to locate the issue

Debian autobuilders already dump config.log when when configuring failed,
and there it is a common problem that people end up searching for the
problem in the wrong places due to that.
It's another story, it is better that autobuilder provide sufficient and
necessary info and data, not only config.log, but also local.conf,
all available log.do_***, sources in ${B} and ${S}, even data in ${WORKDIR},
result of `bitbake -e'
but before we got there, the fix is best choice for do_configure failure
//Hongxu
i
//Hongxu
If possible, it would therefore be better to make it accessible separately.
