cygwin DLL address conflict with version 5.41.6

Module:

Description
Similar to #22104 we're seeing address conflicts loading LangInfo.dll in CI:

      0 [main] perl 13868 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupied
Can't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325.
      0 [main] perl 13870 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupied
Can't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325.
      0 [main] perl 13872 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupied
Can't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325.
      0 [main] perl 13983 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupied
Can't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325.

And rebase shows the conflict:

$ rebase -i `find . -name '*.dll'` ./perl.exe | grep -F '*'
/home/tony/dev/perl/git/perl/cygperl5_41_6.dll                          base 0x00059f6d0000 size 0x010d8000 *
/home/tony/dev/perl/git/perl/lib/auto/I18N/Langinfo/Langinfo.dll        base 0x00059fe80000 size 0x00025000 *

And can be similarly reproduced:

$ ./perl -Ilib -MI18N::Langinfo -efork
      0 [main] perl 16510 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x400000) is already occupied

I plan to prepare a fix and perldelta note PR.

Steps to Reproduce

1. build perl, I've only tested with -DDEBUGGING, there may or may not be a conflict without it
2. run ./perl -Ilib -MI18N::LangInfo -efork

Expected behavior
No error on fork.
