gdb: use foreach_with_prefix in gdb.base/break-interp.exp
Use foreach_with_prefix, instead of foreach and with_test_prefix
separately. Since allows removing some indentation levels, and formats
the test names a bit nicer, in my opinion (or at least, it's more
consistent with the rest of the testsuite):
- PASS: gdb.base/break-interp.exp: LDprelinkNOdebugNO: BINprelinkNOdebugNOpieNO: INNER: core: set verbose on
+ PASS: gdb.base/break-interp.exp: ldprelink=NO: ldsepdebug=NO: binprelink=NO: binsepdebug=NO: binpie=NO: INNER: set verbose on
Note: this patch is better viewed with "git show -w" to ignore
whitespace changes.
gdb/testsuite/ChangeLog:
* gdb.base/break-interp.exp: Use foreach_with_prefix.
