[SailfishDevel] Flatpak for Sailfish

[rinigus]

>From comparing logs of normal apps and the app in Flatpak sasndbox, looks
like sandboxed app does not find /usr/libexec/droid-hybris. Is there a way
to let it search under

>
/usr/lib/arm-linux-gnueabihf/GL/default/libexec/droid-hybris

instead? Any env variable to tune? Seems like HYBRIS_LD_LIBRARY_PATH is
ignored while AT_SECURE is zero.

Corresponding part of strace:

openat(AT_FDCWD,
"/usr/lib/arm-linux-gnueabihf/GL/default/lib/libhybris/linker/o.so",
O_RDONLY|O_LARGEFILE|O_CLOEXEC) = 3
read(3,
"\177ELF\1\1\1\3\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0|\370\0\0004\0\0\0"..., 512)
= 512
fstat64(3, {st_mode=S_IFREG|0755, st_size=221216, ...}) = 0
mmap2(NULL, 306916, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) =

mprotect(0xe2fd4000, 61440, PROT_NONE)  = 0
mmap2(0xe2fe3000, 8192, PROT_READ|PROT_WRITE,

lstat64("/usr/libexec", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
lstat64("/usr/libexec/droid-hybris", 0xfff54d18) = -1 ENOENT (No such file
