perl: fix race issues for MakeMaker
Fixed a race issue when compile libhtml-parser-perl and others who use MakeMaker: [snip] chmod 755 blib/arch/auto/HTML/Parser/Parser.so chmod 644 "Parser.bs" [snip] The rule INST_DYNAMIC removes '.bs' file which are generated by BOOTSTRAP, but the have no dependencies, so there is a race issue: BOOTSTRAP: touch foo.bs chmod 755 foo.bs INST_DYNAMIC: rm -fr foo.bs The error would happen when INST_DYNAMIC removes foo.bs after BOOTSTRAP touched it but before chmod on it.

+Subject: [PATCH] ExtUtils/MM_Unix.pm: fix race issues
+
+Fixed a race issue when compile libhtml-parser-perl and others who use MakeMaker:
+[snip]
+chmod 755 blib/arch/auto/HTML/Parser/Parser.so
+chmod 644 "Parser.bs"
+[snip]
+
+The rule INST_DYNAMIC removes '.bs' file which are generated by BOOTSTRAP, but
+the have no dependencies, so there is a race issue:
+
+BOOTSTRAP:
+ touch foo.bs
+ chmod 755 foo.bs
+
+INST_DYNAMIC:
+ rm -fr foo.bs
+
+The error would happen when INST_DYNAMIC removes foo.bs after BOOTSTRAP touched
+it but before chmod on it.
+
+Upstream-Status: Backport [https://github.com/Perl-Toolchain-Gang/ExtUtils-MakeMaker/commit/44e95e717372abe2b0a6ee55de4b686760b65360]
+
+Note, This is not a real backport, upstream has totally refactored it in one
+patch, please see the link above, it's not a good idea to backport such a big
+patch, I just referred it to fix the problem in a simple way. I mark it as
+backport is because we can drop the patch after upgrade perl to 5.26 or 5.28.
