[PATCH] perf tools: Fix static building

[Alexey Brodkin]

With commit e3d09ec8126f ("tools lib traceevent: Export dynamic symbols
used by traceevent plugins") we started to add "--dynamic-list" in
LDFLAGS. One side-effect of that was inability to build really
statically-linked perf.

I.e. even if "LDFLAGS=-static" were passed on perf building command-line
it had no effect and perf was built dynamically.

This change disables setup of "--dynamic-list" if LDFLAGS contains
"-static" option.
