remove unused extern variables (#2125)
On fc29, compiling bcc from source, the following
compiler warnings are seen:
/home/yhs/work/bcc/src/cc/bcc_elf.c: In function ‘bcc_free_memory_with_file’:
/home/yhs/work/bcc/src/cc/bcc_elf.c:802:36: warning: unused variable ‘_fini’ [-Wunused-variable]
extern unsigned long _start, _fini;
^~~~~
/home/yhs/work/bcc/src/cc/bcc_elf.c:802:28: warning: unused variable ‘_start’ [-Wunused-variable]
extern unsigned long _start, _fini;
^~~~~~
These unused externs are accidentally introduced by
Commit 51480d0597cc ("implement free_bcc_memory() API").
This patch removed them.
