[PATCH] Fix dl-environ.c

[Jakub Jelinek]

Hi!

ld.so has apparently been too aggressive when removing variables
from environment, particularly it removed all the unsecure envvars (as
it should) plus all its prefixes, ie. it removed
LOCALDOMAIN, but e.g. LOCALDOMAI, LOCAL, LOCA, LO or L variables too.

	* sysdeps/generic/dl-environ.c (unsetenv): Only remove variables fully
	matching name.
