GCC: ICU build warnings.

[evoskuil]

https://github.com/libbitcoin/libbitcoin-system/actions/runs/7681642280/job/20949297933?pr=1378#step:8:232

ICU for C/C++ 55.2 is ready to be built.
=== Important Notes: ===
Data Packaging: static
 This means: ICU data will be stored in a static library.
 To locate data: ICU will use the linked data library. If linked with the stub library located in stubdata/, the application can use udata_setCommonData() or set a data path to override.
Building ICU: Use a GNU make such as /usr/bin/gmake to build ICU.
checking the version of "/usr/bin/gmake"... 4.3 (we wanted at least 3.80)
