The original error message from linux-5.17.7/tools/testing/selftests/sgx is
(Note: no global failure in linux-tools/selftests in case one or more of the
test case compiles fail):

  .../host/bin/x86_64-buildroot-linux-gnu-gcc -Wall -Werror -g -I../../../../tools/include -fPIC -z noexecstack -c sigstruct.c -o .../build/linux-5.17.7/tools/testing/selftests/kselftest/sgx/sigstruct.o
  sigstruct.c:15:10: fatal error: openssl/err.h: No such file or directory
     15 | #include <openssl/err.h>
        |          ^~~~~~~~~~~~~~~
  compilation terminated.

You need to enable 'BR2_PACKAGE_OPENSSL' in your defconfig and apply
the following buildroot patch:

--- a/package/linux-tools/linux-tool-selftests.mk.in
+++ b/package/linux-tools/linux-tool-selftests.mk.in
@@ -18,6 +18,10 @@ endif
 
 SELFTESTS_DEPENDENCIES = libcap-ng popt
 
+ifeq ($(BR2_PACKAGE_OPENSSL),y)
+SELFTESTS_DEPENDENCIES += openssl
+endif
+
 SELFTESTS_MAKE_FLAGS = \
        $(LINUX_MAKE_FLAGS) \
        ARCH=$(SELFTESTS_ARCH)
