Yang Jihong a530337ba9 perf build: Fix build feature-dwarf_getlocations fail for old libdw 
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>
