[ Upstream commit 581037151910126a7934e369e4b6ac70eda9a703 ]
This prototype is obtained indirectly, by luck, from some other header
in probe-event.c in most systems, but recently exploded on alpine:edge:
8 13.39 alpine:edge : FAIL gcc version 13.2.1 20240309 (Alpine 13.2.1_git20240309)
util/probe-event.c: In function 'convert_exec_to_group':
util/probe-event.c:225:16: error: implicit declaration of function 'basename' [-Werror=implicit-function-declaration]
225 | ptr1 = basename(exec_copy);
| ^~~~~~~~
util/probe-event.c:225:14: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
225 | ptr1 = basename(exec_copy);
| ^
cc1: all warnings being treated as errors
make[3]: *** [/git/perf-6.8.0/tools/build/Makefile.build:158: util] Error 2
Fix it by adding the libgen.h header where basename() is prototyped.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
