boards/arm/stm32l4: shrink flash for nucleo-l432kc:wgen
The nucleo-l432kc:wgen configuration builds both DAC waveform generator
drivers and testing/ostest, and operates near flash capacity (256 KiB).
Expanding ostest with new tests (e.g. pthread_sigqueue) causes this
configuration to overflow flash by 408 bytes during CI builds
(Linux arm-stm32l-u-g).
Free flash headroom using existing options:
- Disable unused C++ runtime support (CONFIG_HAVE_CXX,
CONFIG_HAVE_CXXINITIALIZE).
- Disable unused NSH commands (basename, cmp, df, dirname, hexdump,
losetup, mkdir, mkrd, mount, rmdir, time, umount, wget, xd).
This frees over 5 KiB of flash space, providing ample headroom for
future testing and libc expansion.
