Subject: libfastjson: add missing runtime dependency on libm
X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=d114f46db11ad1639d9b8c59489182ab9583c092;p=openwrt-packages.git

libfastjson: add missing runtime dependency on libm

libfastjson uses modf() from libm but does not declare the dependency.
With BIND_NOW (CONFIG_PKG_RELRO_FULL), this can cause the dynamic linker
to process libfastjson's relocations before libm's GOT is set up,
triggering a crash in libm's IFUNC resolver on PowerPC.

Fixes: https://github.com/openwrt/packages/issues/29160
