2018-12-15musl: Create default library search path based on configurationSerhey Popovych
In absence of /etc/ld-musl-$(ARCH).path file musl uses hardcoded default search path "/lib:/usr/local/lib:/usr/lib". This works for cases when system libraries installed in one of these pathes. However if lib64 or libx32 used as system library directories and no usr merge functionality enabled for distro musl dynamic loader cannot find libraries and finally execute binaries. Found while working on support for musl on powerpc64 builds where lib64 variant is used regardless of multilib being on or off. Fix by creating default search path based on configuration time values for syslibdir and libdir.

2018-04-07nativesdk-glibc: Split glibc and libcrypt to use libxcrypt insteadRichard Purdie
Fedora28[1] has decided to go ahead and use libxcrypt to replace libcrypt from glibc despite the change not having merged into glibc upstream yet. This breaks the use of uninative in OE on fedora28 since binaries there are now using new symbols only found in libxcrypt. libxcrypt is meant to be backwards compatible with libcrypt but not the reverse. Since this will impact OE in the next release cycle, this changes nativesdk only to use this new model and adds libxcrypt to work in that case. This allows us to build a uninative which is compatible with fedora28 and previous other OSes. In order to work, recipes will now need to depend on virtual/crypt where they use libcrypt since its now a separate library and we can't depend on it from glibc to preseve backwards compatibility since glibc needs to build first. For now, only the problematic nativesdk recipes have been fixed up. For target use, the default provider remains glibc for now. Assuming this change is merged into upstream glibc, we will need to roll this change out for the target but we will do this in the next release cycle when we can better deal with the resulting bugs.

2017-10-16musl: use a more specific fix for ARM thumb + frame pointersAndre McCurdy
When compiling for Thumb or Thumb2, frame pointers _must_ be disabled since the Thumb frame pointer in r7 clashes with musl's use of inline asm to make syscalls (where r7 is used for the syscall NR). In most cases, frame pointers will be disabled automatically due to the optimisation level, but appending an explicit -fomit-frame-pointer to CFLAGS handles cases where optimisation is set to -O0 or frame pointers have been enabled by -fno-omit-frame-pointer earlier in CFLAGS, etc. Note that this limitation applies both to gcc and clang, the only difference between the two being that where gcc aborts with an error about reusing r7, clang apparently silently generates broken code: https://bugs.llvm.org/show_bug.cgi?id=34165 Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
