perf tools: Rename build libperf to perf Rename build libperf to perf, because it's used to build perf. The libperf build object name will be used for libperf library.

perf scripting perl: Ignore some warnings to keep building with perl headers On gcc 12 we started seeing this: In file included from /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/perl.h:2999, from util/scripting-engines/trace-event-perl.c:35: /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/inline.h: In function 'Perl_is_utf8_valid_partial_char_flags': /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/handy.h:125:23: error: cast from function call of type 'STRLEN' {aka 'long unsigned int'} to non-matching type '_Bool' [-Werror=bad-function-cast] 125 | #define cBOOL(cbool) ((bool) (cbool)) | ^ /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/inline.h:2363:12: note: in expansion of macro 'cBOOL' 2363 | return cBOOL(is_utf8_char_helper_(s0, e, flags)); | ^~~~~ In file included from /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/perl.h:7242: /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/inline.h: In function 'Perl_cop_file_avn': /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/inline.h:3489:5: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement] 3489 | const char *file = CopFILE(cop); | ^~~~~ In file included from /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/perl.h:7243: /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/sv_inline.h: In function 'Perl_newSV_type': /usr/lib/perl5/5.36.0/x86_64-linux-thread-multi/CORE/sv_inline.h:376:5: error: enumeration value 'SVt_LAST' not handled in switch [-Werror=switch-enum] 376 | switch (type) { | ^~~~~~ So disable those warnings to keep building with perl devel headers.

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.
