| Subject: [PATCH] Sometimes libsoxr is built to rely on libavutil. If libavutil |
| is detected, link to it when building libsoxr. Add pgk_config support to soxr |
| selection. |

| The Buildroot autobuilder detected a build issue [0] when building |
| shairport-sync statically: |
| |
| ``` |
| arm-buildroot-linux-uclibcgnueabi/sysroot/usr//lib/libsoxr.a(soxr.c.o): In function `soxr_create': |
| soxr.c:(.text+0xd4c): undefined reference to `av_get_cpu_flags' |
| collect2: error: ld returned 1 exit status |
| ``` |
| |
| A quick look at the soxr source code shows that `soxr_create()` might use |
| `av_get_cpu_flags()` depending on the architecture. |
| |
| For the sake of simplicity link with `-lavutil` if it is found when using soxr. |
| |
| Even better, as soxr provides a pkg-config file, this should be prefered. |
