Add two patches to address three distinct build problems spotted by our
build bots when compiling lttng-tools:
1) unconditional use of `__GLIBC_PREREQ`
On musl based toolchains there is no such macro defined, leading to the
following preprocessor error:
CC compat-epoll.lo
In file included from compat-epoll.c:33:0:
poll.h:76:19: error: missing binary operator before token "("
#if __GLIBC_PREREQ(2, 9)
2) undeclared `mode_t` type
On musl based toolchains the `mode_t` type is not implicitely defined through
other includes, leading to the following compile error:
CC hashtable.lo
In file included from ../../../src/common/common.h:24:0,
from hashtable.c:24:
../../../src/common/runas.h:25:46: error: unknown type name 'mode_t'
int run_as_mkdir_recursive(const char *path, mode_t mode, uid_t uid, gid_t gid);
^
../../../src/common/runas.h:26:36: error: unknown type name 'mode_t'
int run_as_mkdir(const char *path, mode_t mode, uid_t uid, gid_t gid);
^
../../../src/common/runas.h:27:46: error: unknown type name 'mode_t'
int run_as_open(const char *path, int flags, mode_t mode, uid_t uid, gid_t gid);
^
3) multiple definitions
The header files declare several `const char *` pointers which are initialized
in various `*.c` files later on. Due to a missing `extern` declaration in the
header, the final linking of the executables fails with errors such as:
CCLD lttng
../../../src/common/.libs/libcommon.a(mi-lttng.o):(.data.rel.ro.local+0x0): multiple definition of `mi_lttng_element_snapshots'
commands/enable_events.o:(.bss+0x18): first defined here
collect2: error: ld returned 1 exit status
This commits addresses these issues with two patches, `100-musl-compat.patch`
fixes issue 1 by declaring a fallback dummy declaration of `__GLIBC_PREREQ` and
issue 2 by explicitely including `sys/stat.h` which provides `mode_t` according
to POSIX.
The second patch, `200-use-extern.patch` declares all char pointers in the
header file as `extern`, fixing the observed linker errors.

OpenWrt packages feed
Description
This is the OpenWrt "packages"-feed containing community-maintained build scripts, options and patches for applications, modules and libraries used within OpenWrt.
Installation of pre-built packages is handled directly by the opkg utility within your running OpenWrt system or by using the OpenWrt SDK on a build system.
Usage
This repository is intended to be layered on-top of an OpenWrt buildroot. If you do not have an OpenWrt buildroot installed, see the documentation at: OpenWrt Buildroot – Installation on the OpenWrt support site.
This feed is enabled by default. To install all its package definitions, run:
./scripts/feeds update packages
./scripts/feeds install -a -p packages
