perf tools: Fix build failure on perl script context
On my Archlinux machine, perf faild to build like below: CC scripts/perl/Perf-Trace-Util/Context.o In file included from /usr/lib/perl5/core/perl/CORE/perl.h:3905:0, from Context.xs:23: /usr/lib/perl5/core/perl/CORE/inline.h: In function : /usr/lib/perl5/core/perl/CORE/cop.h:612:13: warning: declaration of 'av' shadows a previous local [-Werror-shadow] AV *av =3D GvAV(PL_defgv); ^ /usr/lib/perl5/core/perl/CORE/inline.h:526:5: note: in expansion of macro 'CX_POP_SAVEARRAY' CX_POP_SAVEARRAY(cx); ^~~~~~~~~~~~~~~~ In file included from /usr/lib/perl5/core/perl/CORE/perl.h:5853:0, from Context.xs:23: /usr/lib/perl5/core/perl/CORE/inline.h:518:9: note: shadowed declaration is here AV *av; ^~ What I did to fix is adding '-Wno-shadow' as the error message said it's the cause of the failure. Since it's from the perl (not perf) code base, we don't have the control so I just wanted to ignore the warning when compiling perl scripting code. Committer note: This also fixes the build on Fedora Rawhide.
