Subject: [PATCH] musl: backport O_LARGE fix

musl 1.2.2 started defining O_LARGEFILE to an actual value for x86_64, which breaks the firefox seccomp filter when built with older musl headers. backporting this change and building firefox with it allows one to use a local more up to date musl version with firefox from repos

+
+prior to commit 685e40bb09f5f24a2af54ea09c97328808f76990, x86_64 was
+correctly passing O_LARGEFILE to SYS_open; it was removed (defined to
+0 in the public header, and changed to use the public definition) as
+part of that change, probably out of a mistaken belief that it's not
+needed.
+
+however, on a mixed system with 32-bit and 64-bit binaries, it's
+important that all files be opened with O_LARGEFILE, even if the
+opening process is 64-bit, in case a descriptor is passed to a 32-bit
+process. otherwise, attempts to access past 2GB in the 32-bit process
+could produce EOVERFLOW.
+
+most 64-bit archs added later got this right alread, except for
+mips64. x32 was also affected. there are now fixed.
