uboot-envtools: Add TARGET_LDFLAGS to fix PIE and RELRO

Browse Source 
Forward the OpenWrt TARGET_LDFLAGS to the linker of the fw_printenv tool.
In addition also use the more standard make invocation script.
With this change the fw_printenv tool is built with PIE and Full RELRO
support when activated globally in OpenWrt.
