Sorry, I left out the following configuration options during copy-paste:
--prefix=/home/eus/gcc-9 --srcdir=/home/eus/gcc-9

Thank you, I am aware of that.  I did not parallelize the build on
purpose to compare the total time with the previous
non-profiledbootstrap build.

Any idea on how to find out the cause of the missing Makefile?  I
attach the config.log file that I found under
`$buildir/x86_64-linux-gnu/libstdc++-v3/' as there is only one
config.log file under that directory according to: find
/homd/eus/buildzone/gcc-9-build/x86_64-linux-gnu/libstdc++-v3/ -iname
'*.log*', and the attached file ends with: configure: exit 0.

Thank you.
