H. Nikolaus Schaller 15ae05c2ee mips: Fix non-POSIX regexp 
[ Upstream commit 28bbbb9875a35975904e46f9b06fa689d051b290 ]

When cross compiling a MIPS kernel on a BSD based HOSTCC leads
to errors like

  SYNC    include/config/auto.conf.cmd - due to: .config
egrep: empty (sub)expression
  UPD     include/config/kernel.release
  HOSTCC  scripts/dtc/dtc.o - due to target missing

It turns out that egrep uses this egrep pattern:

		(|MINOR_|PATCHLEVEL_)

This is not valid syntax or gives undefined results according
to POSIX 9.5.3 ERE Grammar

	https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html

It seems to be silently accepted by the Linux egrep implementation
while a BSD host complains.

Such patterns can be replaced by a transformation like

	"(|p1|p2)" -> "(p1|p2)?"

Fixes: 48c35b2d24 ("[MIPS] There is no __GNUC_MAJOR__")
