[PATCH 6.0 025/157] LoongArch: Makefile: Use "grep -E" instead of "egrep"

From: Tiezhu Yang <yangtiezhu@loongson.cn>

[ Upstream commit 83f638bca0ccd94942bc3c4eb9bcec24dd8a1cf9 ]

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E

Fix this up by changing the LoongArch Makefile to use "grep -E" instead.
