Frank Ch. Eigler 4eb048d448 binutils testsuite: canonicalize subtest names in libctf
Previous code included the full $srcdir pathnames in the individual
subtest PASS/FAIL names, which makes it difficult to compute
comparisons or regressions between test runs on different machines.
This version switches to the basename only, which are common.

# run_lookup_test FILE
#
# Compile with the host compiler and link a .c file into a "lookup" binary, then
# compile and optionally link together a bunch of .s or .c files with CTF info
# and pass the name of the resulting binary to the "lookup" binary and check the
# output. (If none is specified, the binary is expected to generate its own CTF
# for testing purposes.)
#
# As with run_dump_test, this is all driven by a file (in this case, a .lk file)
# beginning with zero or more option lines, which specify the names of the
# lookup binary's source file, the source file(s) with CTF info to compile
# together, and whether to link them. The optional lines have the syntax:
#
# # OPTION: VALUE
#
# OPTION is the name of some option, like "name" or "lookup", and
# VALUE is OPTION's value. The valid options are described below.
# Whitespace is ignored everywhere, except within VALUE. The option
# list ends with the first line that doesn't match the above syntax.
# However, a line within the options that begins with a #, but doesn't
# have a recognizable option name followed by a colon, is considered a
# comment and entirely ignored.
#
# The interesting options are:
#
# name: TEST-NAME
# The name of this test, passed to DejaGNU's `pass' and `fail'
# commands. If omitted, this defaults to FILE, the root of the
# lookup .c file's name.
#
# lookup: SOURCE
# Compile the file SOURCE.c. If omitted, the lookup source defaults
# to FILE.c.
#
# source: SOURCE
# Assemble the file SOURCE.c and pass it to the LOOKUP program.
#
# nonshared:
# If set, do not link with -shared.
#
# link:
# If set, link the SOURCE together even if only one file is specified.
#
# link_flags:
# If set, extra flags to pass to the linker.
#
# lookup_link:
# If set, extra libraries to link the lookup program with.
#
# xfail: GLOB|PROC ...
# This test is expected to fail on a specified list of targets.
#
# no_cross:
# If set, do not run this test when host != target.
#
# host:
# If set, only run this test on hosts matching the given glob.
#
# wrapper:
# Wrap invocations of LOOKUP in this command. (Useful for valgrind
# invocations, etc.)
#
# Each option may occur at most once unless otherwise mentioned.
#
# After the option lines come regexp lines. run_lookup_test calls
# regexp_diff to compare the output of the lookup program against the
# regexps in FILE.d.
