build: debug: strace: Add -D__USE_MISC to target CFLAGS

Browse Source 
Similar to commit ca45a8f9 ("Add -D__GLIBC__ to target CFLAGS") newer
versions of strace bundle the kernel headers which cause build errors
such as:

[ALL  ]    In file included from /home/x-tool/.build/arm-unknown-linux-musleabi/src/strace/bundled/linux/include/uapi/linux/in6.h:26,
[ALL  ]                     from /home/x-tool/.build/arm-unknown-linux-musleabi/src/strace/bundled/linux/include/uapi/linux/if_bridge.h:19,
[ALL  ]                     from /home/x-tool/.build/arm-unknown-linux-musleabi/src/strace/src/rtnl_mdb.c:16:

[ALL  ]          |
[ALL  ]    cc1: all warnings being treated as errors

By defining __USE_MISC we get __UAPI_DEF_IN6_ADDR_ALT defined in a
compatible manner.
