[Buildroot] [PATCH 4 of 9 v4] Remove redundant dollar signs in Config.in files

[Thomas De Schampheleire]

Some Config.in(.host) files have constructs like:

config FOO_VERSION
	string
	default "1.0" if FOO_1_0
	default "2.0" if FOO_2_0
	default $FOO_CUSTOM_VERSION if FOO_CUSTOM

The dollar sign here is not needed and confusing, so can be removed.
