Thanks for your suggestions, Nick!

In fact, as Jan already mentioned, I can get the contents
of the named section with the help of
objcopy --dump-section secname=secoutfile ...

And I need redirect the output to null (I don't need it),
because I cannot get raw output for this section
by using --output-target, see my reply
https://sourceware.org/pipermail/binutils/2024-January/132041.html

This solutions needs an intermediate file in the comparison
with non-platform-independent solution, but more simple:
readelf -p secname | grep sometext

And I don't need the strings utility, because
I know the content of this section is a ASCII text with spaces
that was added with the command:
objcopy --add-section secname=secfile --set-section-flags
secname=noload,readonly ...
