package/php: fix date.timezone

In 5f37843a (php.ini: set date.timezone), the configured timezone was
used as the default for PHP.

However, BR2_TARGET_LOCALTIME is a string, so is quoted, so it is never
empty, so the check for emptynessnever matches.

Fix that by q-stripping the value before testing it. Note however that
we do not q-strip it before storing it in the php.ini file, because it
has to be q-stripped in there.

Applied to master, thanks.

 That's actually not correct. The idea is that it should be possible to run:

make BR2_TARGET_LOCALTIME="UTC"

in which case the variable will _not_ have quotes. Therefore, everywhere in
Buildroot, we do something like:

PHP_LOCALTIME = "$(call qstrip,$(BR2_TARGET_LOCALTIME))"

 Note BTW that we already have

TZ_LOCALTIME = $(call qstrip,$(BR2_TARGET_LOCALTIME))
TZDATA_LOCALTIME = $(call qstrip,$(BR2_TARGET_LOCALTIME))

so perhaps it would make sense to move this qstripping to global scope...

 Arnout

Arnout, All,

No, please no...I am absolutely against allowing this.

It is OK for things like BR2_DL_DIR or BR2_DEFCONFIG, for which we have
explicit handling and does not "leak" into the target filesystem.

However, for configuration variables that affect the target filesystem,
I think we should not allow specifying them on the command line at all.
Or what, we could pass any-and-all options on the command line? Noooo...

Configuration variables that affect the content of the target filesystem
should all be confined to the .config file.

However, there is a remaining bug lurking around (see below).

Yes, maybe... I'll see to it.

Here, UTC is not quoted... I'll fix that.
