Fix for failing tests on Solaris

Fix for failing tests on Solaris

[Vladimir Marek]

Hello,

Sorry if this is not the best way to report issues.

Solaris ships git[1]. We run it's test suite and we were having multiple
failures[2]. I noticed that the tests do expect binaries to be found
in [3]:

SANE_TOOL_PATH = /usr/xpg6/bin:/usr/xpg4/bin

That paths contain posix conformant binaries, but the tests do expect
Linux-like behaving binaries.

The patch I am about to apply to git

--- git-2.35.1/config.mak.uname
+++ git-2.35.1/config.mak.uname

        NO_MEMMEM = YesPlease

Makes all tests but t7812 pass successfully. t7812 fails on locales and
utf-8 which do behave differently in Solaris.

I would suggest to update the tests to use /usr/gnu/bin path.

Expecting Linux-like behaviour is indeed not what the tests should be
doing, so correcting that might ALSO help other people that don't have
an alternative GNU implementation available IMHO

So detailing those failures and fixing them might be preferable (even if
likely more difficult)

I haven't used Solaris for a while (since around OpenSolaris Indiana
development stopped), but wouldn't this break in Solaris 10 and older?

And additional fix for that (since you seem to have access to a fresh
Solaris 11.4 installation at least), would be forthcomming.

Wondering also if there is a way to plug one of those from Oracle Cloud
through a GitHub actions so we could prevent future issues by including
Solaris in our CI runs.

I do not think we want to take this patch until we know how exactly
the tests failing for Vladimir fail without GNUism, which we do not
want to rely on.  If a test by mistake used "sed -i -e '<script>'"
GNUism which /usr/xpg[46]/bin/sed does not support, for example, we
want to know about it, so that we can move away from such a use of
GNUism.

Thanks.
