openssl-1.1.1b: Compilation errors when use async and ct

[Samiya Khanum via openssl-users <openssl-users@xxxxxxxxxxx>]

Hi,

While compiling async I see below errors with UCLIBC.

libcrypto.so: undefined reference to `getcontext'
libcrypto.so: undefined reference to `setcontext'
libcrypto.so: undefined reference to `makecontext'

As UCLIBC doesn't have support to these APIs, i have added no-async in configure. With no-async below errors are seen.

libcrypto.so: undefined reference to `ERR_load_ASYNC_strings'
libcrypto.so: undefined reference to `async_init'
libcrypto.so: undefined reference to `async_delete_thread_state'
libcrypto.so: undefined reference to `async_deinit'

Do we need to have macro check" #ifndef OPENSSL_NO_ASYNC" before these api calls?

Similarly for CT, we are seeing below errors. With no-ct options, compilation is OK.

We would like to know what would be the impact if we disable async and ct features. Could you please help us in understanding these features.
