Metzger, Markus T Feb. 6, 2018, 1:10 p.m. UTC 
  In gdb.btrace/buffer-size.exp we explicitly ask for the BTS recording format.
This may lead to spurious fails on systems where PT is being used by some other
process at the same time.

Set both PT and BTS buffer sizes to 1 and check that whatever recording format
is used will use a 4KB buffer.

	* gdb.btrace/buffer-size.exp: Do not force BTS.
