fix(aarch64): Fix build failure on ARM architecture chips

[acelyc111]

Fix build failures like:

/bin/ld: /.../thirdparty/output/lib/libcurl.a(libcurl_la-content_encoding.o): in function `brotli_close_writer':
content_encoding.c:(.text+0x2c): undefined reference to `BrotliDecoderDestroyInstance'

/bin/ld: /.../thirdparty/output/lib/libcurl.a(libcurl_la-easy.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `malloc' which may bind externally can not be used when making a shared object; recompile with -fPIC
/bin/ld: /.../thirdparty/output/lib/libcurl.a(libcurl_la-easy.o)(.text+0x30): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `malloc'

/bin/ld: idn.c:(.text+0x34): undefined reference to `idn2_lookup_ul'
