Comment 6 for bug 1179359

The problem is: mysqld-debug vs mysqld, and it happens only on debug + valgrind/debug binaries:

===================
[roel@qaserver Percona-Server-5.6.11-alpha60.3-372-debug.Linux.x86_64]$ ./scripts/mysql_install_db --no-defaults --basedir=/ssd/Percona-Server-5.6.11-alpha60.3-372-debug.Linux.x86_64 --datadir=/ssd/Percona-Server-5.6.11-alpha60.3-372-debug.Linux.x86_64/data
FATAL ERROR: Could not find

If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

===================

And it's clear from the source it doesn't check for mysqld-debug:

===================
-x $mysqld or -f "$mysqld.exe" or cannot_find_file($mysqld);
# Try to determine the hostname
my $hostname = hostname();
===================

Unless there is a good/specific reason, I would like to ask we not use mysql-debug in any case, it unnecessarily complicates testing in various ways.
