-## Usage: $(call remove_enabled_options_crypto,PREPROCESSOR_INPUT)
-## Remove the preprocessor symbols that are set in the current configuration
-## from PREPROCESSOR_INPUT. Also normalize whitespace.
-## Example:
-##   $(call remove_enabled_options_crypto,MBEDTLS_FOO MBEDTLS_BAR)
-## This expands to an empty string "" if MBEDTLS_FOO and MBEDTLS_BAR are both
-## enabled in the TF-PSA-Crypto configuration, 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.
