Apparently I misread the github changelog: our uclinux patch was not
applied to the 7.6.0 release, we still need the backported patch, sorry.

+Subject: [PATCH] configure: match uclinux pattern
+
+BDWGC does not recognize "uclinux" as a valid OS part of the target
+tuple which is used by some arm cortex-M toolchains.
+
+* configure.ac [$THREADS=pthreads] (GC_LINUX_THREADS, _REENTRANT): Define
+for hosts matching "*-*-*linux*" (instead of "*-*-linux*").
