abseil: Revert last commit and use *.pc instead
As pointed out by wiz, *.pc can be used. This
makes the list useless and handling of pc files
even easier.

abseil: add pkg-config overrides and ease their maintainance
Add pkg-config overrides, add them to a separate file due
to the big amount. Also add a target that can update this
file when doing package updates.

Log message:
abseil: updated to 20230802.1

Abseil LTS 20230802.1

Added the nullability library for designating the expected nullability of \ 
pointers. Currently these serve as annotations only, but it is expected that \ 
compilers will one day be able to use these annotations for diagnostic purposes.
Added the prefetch library as a portable layer for moving data into caches \ 
before it is read.
Abseil's hash tables now detect many more programming errors in debug and \ 
sanitizer builds.
Abseil's synchronization objects now differentiate absolute waits (when passed \ 
an absl::Time) from relative waits (when passed an absl::Duration) when the \ 
underlying platform supports differentiating these cases. This only makes a \ 
difference when system clocks are adjusted.
Abseil's flag parsing library includes additional methods that make it easier to \ 
use when another library also expects to be able to parse flags.
absl::string_view is now available as a smaller target, \ 
@com_google_absl//absl/strings:string_view, so that users may use this library \ 
without depending on the much larger @com_google_absl//absl/strings target.

What's New:

The Abseil logging library has been released. This library provides facilities \ 
for writing short text messages about the status of a program to stderr, disk \ 
files, or other sinks (via an extension API). See the logging library \ 
documentation for more information.
An extension point, AbslStringify(), allows user-defined types to seamlessly \ 
work with Abseil's string formatting functions like absl::StrCat() and \ 
absl::StrFormat().
A library for computing CRC32C checksums has been added.
Floating-point parsing now uses the Eisel-Lemire algorithm, which provides a \ 
significant speed improvement.
The flags library now provides suggestions for the closest flag(s) in the case \ 
of misspelled flags.
Using CMake to install Abseil now makes the installed artifacts (in particular \ 
absl/base/options.h) reflect the compiled ABI.

Breaking Changes:

Abseil now requires at least C++14 and follows Google's Foundational C++ Support \ 
Policy. See this table for a list of currently supported versions compilers, \ 
platforms, and build tools.
The legacy spellings of the thread annotation macros/functions (e.g. \ 
GUARDED_BY()) have been removed by default in favor of the ABSL_ prefixed \ 
versions (e.g. ABSL_GUARDED_BY()) due to clashes with other libraries. The \ 
compatibility macro ABSL_LEGACY_THREAD_ANNOTATIONS can be defined on the compile \ 
command-line to temporarily restore these spellings, but this compatibility \ 
macro will be removed in the future.

Known Issues

The Abseil logging library in this release is not a feature-complete replacement \ 
for glog yet. VLOG and DFATAL are examples of features that have not yet been \ 
released.
