faster to compile.
A small selection of packages was tested going from:

usr time 82.98 mins 395.00 micros 82.98 mins
sys time 9.02 mins 0.00 micros 9.02 mins

sys time 8.85 mins 57.00 micros 8.85 mins
Tested by running make -j 12 and wiping staging/build_dir/target_x

musl doesn't support fts. But with the extra package musl-fts installed,
libzip picks up the fts header and fails at the linking stage:
zipcmp.c:(.text.startup+0x130): undefined reference to `fts_open'
/home/sk/tmp/openwrt/staging_dir/toolchain-mips_24kc_gcc-8.3.0_musl/lib/gcc/mips-openwrt-linux-musl/8.3.0/../../../../mips-openwrt-linux-musl/bin/ld: zipcmp.c:(.text.startup+0x172): undefined reference to `fts_read'
So with musl-fts we need to link in libfts. To address that this commits
patches the cmake setup to check if fts is available in libc itself or
in any external libfts.
So when musl-fts is installed on the system the setup will be the
following:
musl: use libfts
uclibc: use fts from libc
glibc: like uclibc
