Undefined $SED in configure

[albandil]

When I configure the v5.0.0rc7 tag from the repository on openSUSE Tumbleweed (with up to date submodules and autogen.pl executed), I see this output:

(...)
*** Fortran compiler
checking whether the compiler supports GNU Fortran... yes
checking whether gfortran-12 accepts -g... yes
checking for BSD- or MS-compatible name lister (nm)... ../../configure: line 32694: 1q: command not found

../../configure: line 32700: 1q: command not found

(...)

The lines 32694 and 32700 are similar and both contain $SED '1q'. The content of the variable $SED is apparently empty. Only when I do

SED=sed ./configure

then the configuration finishes without complaints. Open MPI, PMIX, as well as PRTE seem to be affected by the same problem; I see the same set of command-not-found messages three times.

Thanks for the report!

some AC_PROG_SED calls are missing in various configure.ac

I also noted lex library detection is busted on Tumbleweed:
/usr/lib64/libfl.so expects a yylex symbol but it is not defined in the conftest.c generated by autotools.

I will issue the PRs and check the flex detection issue later on.

Fixed by #10400 (main) and #10406 (v5.0.x)
