/home/smarchi/src/lttng-tools/src/common/compat/string.h: In function ‘lttng_strndup’:
/home/smarchi/src/lttng-tools/src/common/compat/string.h:78:8: error: implicit declaration of function ‘malloc’ [-Werror=implicit-function-declaration]

/home/smarchi/src/lttng-tools/src/common/compat/string.h:78:8: error: incompatible implicit declaration of built-in function ‘malloc’ [-Werror]
/home/smarchi/src/lttng-tools/src/common/compat/string.h:78:8: note: include ‘<stdlib.h>’ or provide a declaration of ‘malloc’

Note that this is in fallback code when the system doesn't provide
strndup (or, in my case, the system provides it but configure failed to
find it).
