[Libreoffice] [PATCH] remove -d from gunzip flags

Hello,

It's also possible to replace gunzip by gzip like the other lines of 
this file :
# unpack the Crystal icon set
$(MISC)$/crystal.flag : $(CRYSTAL_TARBALL)
    cd $(MISC) && gzip -d -c $(CRYSTAL_TARBALL) | ( tar -xf - ) && 
$(TOUCH) $(@:f)

# unpack the Oxygen icon set
$(MISC)$/oxygen.flag : $(OXYGEN_TARBALL)
    cd $(MISC) && gzip -d -c $(OXYGEN_TARBALL) | ( tar -xf - ) && 
$(TOUCH) $(@:f)

so we'd have :
# unpack the classic icon set
$(MISC)$/classic.flag : $(CLASSIC_TARBALL)
    cd $(MISC) && gzip -d -c $(CLASSIC_TARBALL) | ( tar -xf - ) && 
$(TOUCH) $(@:f)
