Hi,

this was reverted. (There was no actual LTO usage anywyay ttbomk).

- It missed a chmod 755 so  that clang_wrapper was executable

  This was fixed in 1:7.2.0-3

- configure doesn't detect any clang and uses g++
  (cf.
  https://buildd.debian.org/status/fetch.php?pkg=libreoffice&arch=amd64&ver=1%3A7.2.0-3%2Bb1&stamp=1630963567&raw=0):

clang: error: -E or -x required when input is from standard input
configure: WARNING: "" is too old or unrecognized, must be at least Clang 5.0.2
configure: WARNING: Clang compiler not found.

  (or - worse - fails directly if one actually wants to use clang as
  main compiler):
