For libdw versions below 0.177, need to link libdl.a in addition to
libbebl.a during static compilation, otherwise
feature-dwarf_getlocations compilation will fail.
Before:
$ make LDFLAGS=-static
BUILD: Doing 'make -j20' parallel build
<SNIP>
Makefile.config:483: Old libdw.h, finding variables at given 'perf probe' point will not work, install elfutils-devel/libdw-dev >= 0.157
<SNIP>
$ cat ../build/feature/test-dwarf_getlocations.make.output
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/libebl.a(eblclosebackend.o): in function `ebl_closebackend':
(.text+0x20): undefined reference to `dlclose'
collect2: error: ld returned 1 exit status
After:
$ make LDFLAGS=-static
<SNIP>
Auto-detecting system features:
... dwarf: [ on ]
<SNIP>
$ ./perf probe
Usage: perf probe [<options>] 'PROBEDEF' ['PROBEDEF' ...]
or: perf probe [<options>] --add 'PROBEDEF' [--add 'PROBEDEF' ...]
or: perf probe [<options>] --del '[GROUP:]EVENT' ...
or: perf probe --list [GROUP:]EVENT ...
<SNIP>
