cmReadGccDepfile() calls cmSystemTools::CollapseFullPath(), which
is not thread safe due to internal caching. Serialize calls to
cmReadGccDepfile() in autogen to avoid thread safety issues.

Refactoring in commit 4c74c86f40 (FindBLAS/LAPACK: Add support for the
Fujitsu SSL2 library, 2021-01-27) was done in order to support calling
`find_library` on the dependencies as well as the candidate libraries.
However, it broke a few things:
* Intel MKL's BLAS/LAPACK are no longer found. We specify their
dependencies using `-l...` flags, so we should not try to use
`find_library` for them.
* The dependencies are repeated because we accumulate them in the
`find_library` search loop and then append them at the end too.
Revert the incorrect part of the refactoring. Retain the flags part
needed for the Fujitsu vendor.
Fixes: #22056
KWSys as of 2021-04-14 changed the return type of `SystemTools`
operations from `bool` to `Status`. Update our call sites.
This may improve error reporting accuracy in a few places.

Since commit f034b0f663 (CMake compilation: do not use compiler
extensions, 2020-03-14, v3.18.0-rc1~494^2), some sources explicitly
enable needed system APIs on some platforms using definitions like
`_POSIX_C_SOURCE` and `_XOPEN_SOURCE`. Drop the definitions for
OpenBSD, which provides the POSIX APIs by default.

This facility is very useful for 'Ninja Multi-Config' and required
as well for future support of DEPFILE in 'Xcode' and 'Visual Studio'
generators (#20286).
This is achieved by adding a rule file which carries the UI files as dependencies but performs no meaningful command. Its output path points to a timestamp file which is instead touched by the pre-build command that runs autogen. The rule file therefore triggers the build if any of the files have been changed more recently than the last autogen run.
