dlsym.cpp:(.text+0x34): undefined reference to `__libc_dlopen_mode'

+Subject: [PATCH] gltrace: Avoid __libc_dlsym and __libc_dlopen_mode on GLIBC
+ 2.34.
+
+These GLIBC_PRIVATE symbols are gone from GLIBC 2.34 due to the merge of
+libdl.so onto libc.so.
+
+This means apitrace can't defend against infinite recursion when
+used with Steam Overlay, but at least it should work otherwise.
