[committed] contrib: Quote variable in test expression [PR111360]

[Jonathan Wakely]

Committed as obvious.

-- >8 --

Without the quotes some shells will always return true and some will
print an error. It should be quoted so that a null variable works as
intended.

contrib/ChangeLog:

	PR other/111360
	* gcc_update: Quote variable.
