Reusing those variables is common in layers dealing with multiple toolchains, 
such as external binary toolchains and such. Might be good to keep them in 
OE-Core for consistency:

GCCVERSION ?= "9.%"
SDKGCCVERSION ?= "${GCCVERSION}"
BINUVERSION ?= "2.34%"
GDBVERSION ?= "9.%"
GLIBCVERSION ?= "2.31%"
LINUXLIBCVERSION ?= "5.4%"
