As reported by Laine Gholson (you can find emerge --info and complete build log at https://archives.gentoo.org/gentoo-musl/message/ae11c600384656ea575748179fd8d8f9 ) compiling sys-boot/vboot-utils on the musl profiles leads to the compilation error:
firmware/stub/vboot_api_stub_sf.c:8:22: fatal error: execinfo.h: No such file or directory
I had forgotten that to make it work, also the ebuild needs to be
modified to pass HAVE_MUSL to make when elibc_musl.
I've added a new snapshot which includes the upstream patch, and updated the ebuild to pass HAVE_MUSL=1 in the make arguments:
fyi, i've broken out libubacktrace from uclibc and will be adding it to the tree. the work is at https://github.com/blueness/libubacktrace-standalone. once that's in tree, we can avoid patches like this.
