In gsub, when the destination string is empty, the string 't' is
provided and the regular expression doesn't match, then the final result
is an empty string.

Example:

=> echo ${foo}

=> setenv foo
=> setexpr foo gsub e a bar
=> echo ${foo}

=>

The variable ${foo} should contain "bar" and the lack of match shouldn't
be considered an error.

This patch fixes the erroneous behavior by removing the return
statement and breaking out of the loop in case of lack of match.

Also add a test for the no match case.

The font test needs two fonts. If one is not available, skip out early,
to avoid an error.

The error that this test checks for is only shown on sandbox. For real
boards, there is normally no error. Add a special case to handle this.

Calling into sub-test functions should be done using ut_assertok() so
that the test exits immediately on failure. Add those which are
missing.

This test assumes that the stack pointer is the same across two calls
to lmb_init_and_reserve() but this is not the case on x86, for example.

Add a special case to handle this, along with a detailed comment.

Add a new suite for 'cmd' tests, used for testing commands. These are
kept in the test/cmd directory.

For now it is empty, but it will be used for coreboot-command tests.

Systems without getopt support fall back to plain full bdinfo print,
handle such a case, which occurs e.g. with sandbox_flattree_defconfig .
