Raise the minimum binutils version to 2.39

The recent commit 27b96e069aad17cefea9437542180bff448ac3a0 raises the minimum
GCC version to 12.1 which was released in 2022.

The current minimum bintuils version 2.25 was released end of 2014.  This patch
now raises the minimum binutils version to 2.39 which was also released in 2022.

The hint for ARC is not needed anymore.

In sysdeps/[alpha|hppa|csky]/configure.ac, PIE is unsupported with this comment:
PIE builds fail on binutils 2.37 and earlier, see:
https://sourceware.org/bugzilla/show_bug.cgi?id=28672
This patch keeps PIE unsupported and let the machine maintainers test and
enable it later.

In sysdeps/arm/configure.ac, there is a check whether TPOFF relocs with addends
are assembled correctly, which is known to be broken in binutils 2.24 and 2.25.
See: https://sourceware.org/bugzilla/show_bug.cgi?id=18383
This patch keeps the check as is and let the machine maintainers check if it
still required.

According to Florian Weimer:
Having at least binutils 2.38 will allow us to assume that this linker
bug is fixed:
