wolfssl requires definition of SIZEOF_LONG_LONG. Commit 3a5e071e4f9
("package/libcurl: security bump to version 8.19.0") removed
SIZEOF_LONG_LONG definitions from libcurl autotools build system,
breaking build with wolfssl.

Fixes:

although the problem should be fixed in wolfSSL instead, see

for details.

+Subject: [PATCH] Define HAVE_LIMITS_H in options.h rather than config.h since
+ types.h depends on this definition and config.h isn't consistently available
+ at runtime. Fixes #9936.
