When building with Make on a Unix-like platform (shell and compiler), auto-detect configurations that may require linking with pthread. This removes the need for MAKE_THREADING_FLAGS in all.sh. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>

## Usage: $(call remove_unset_options,PREPROCESSOR_INPUT)
|
|
## Remove the preprocessor symbols that are not set in the current configuration
|
|
## from PREPROCESSOR_INPUT. Also normalize whitespace.
|
|
## Example:
|
|
## $(call remove_unset_options,MBEDTLS_FOO MBEDTLS_BAR)
|
|
## This expands to an empty string "" if MBEDTLS_FOO and MBEDTLS_BAR are both
|
|
## disabled, 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.
