+## Usage: $(call remove_enabled_options,PREPROCESSOR_INPUT)
+## Remove the preprocessor symbols that are set in the current configuration
+## from PREPROCESSOR_INPUT. Also normalize whitespace.
+## Example:
+##   $(call remove_enabled_options,MBEDTLS_FOO MBEDTLS_BAR)
+## This expands to an empty string "" if MBEDTLS_FOO and MBEDTLS_BAR are both
+## enabled, to "MBEDTLS_FOO" if MBEDTLS_BAR is enabled but MBEDTLS_FOO is
+## disabled, etc.
+##
+## This only works with a Unix-like shell environment (Bourne/POSIX-style shell
+## and standard commands) and a Unix-like compiler (supporting -E). In
+## other environments, the output is likely to be empty.
