devel/bossa: fix build with clang 18
Clang 18 has a new warning about variable length arrays used in C++,
which is emitted when building devel/bossa:
src/Flasher.cpp:115:28: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension]
115 | uint8_t buffer[bufferSize];
| ^~~~~~~~~~
src/Flasher.cpp:115:28: note: read of non-const variable 'bufferSize' is not allowed in a constant expression
src/Flasher.cpp:114:22: note: declared here
114 | uint32_t bufferSize = _samba.writeBufferSize();
| ^
[... more of these ...]Since refactoring the code to no longer use VLAs is rather intrusive,
suppress the warnings instead.
While here, pet portlint.
